How long does it take to use OvuFriend menstrual calendar?

Just a few minutes a day to complete information about your health, cycle, mood or symptoms. But it all depends on you and your goal. 

If you use OvuFriend to prepare for pregnancy, get pregnant or are undergoing infertility treatment, it is worthwhile for you to spend some more time on recording information. The more information you provide, the better OvuFriend will learn your fertility. 

Similarly, if you feel something that worries you, e.g. low libido, abdominal pain, spotting, or heavy bleeding, then in addition to the obvious consultation with your doctor, it is worthwhile for you to take some time and note down your symptoms and information about your menstrual cycle in the application on a daily basis for at least 3 cycles. 

If you use OvuFriend to track your cycles, to know when your last menstruation occurred, to know if your cycles are regular and to have your fertility under control, it is probably enough to log the most important parameters of your cycle once in a while, i.e. menstrual bleeding, cervical mucus or the symptoms you feel, which you consider important. The system analyzes the information you enter on an ongoing basis. 

At OvuFriend you will be supported by a digital health assistant, which will give you personalized tips, hints and ask for relevant information about your cycles and fertility if needed for your cycles and health evaluation.

 

Is OvuFriend reliable? Can I trust it?

Yes - OvuFriend is an effective and reliable fertility tracking app you can trust. Its accuracy comes from combining science, artificial intelligence algorithms, big-data analysis, and the expertise of top gynecology, endocrinology, and nutrition specialists.

OvuFriend works by:

  • Using machine-learning algorithms – analyzing your individual menstrual cycle and adjusting ovulation and fertile-day predictions specifically for you.
  • Leveraging a huge database of women’s cycles – the app learns from millions of data points, making its predictions far more precise than standard fertility calendars.
  • Basing its recommendations on medical knowledge – all solutions are developed with expert input and follow medical society guidelines for women’s health and fertility.
  • Incorporating your daily observations – every piece of data you log (temperature, cervical mucus, symptoms) makes the app smarter and more tailored to you.
  • Offering a fully personalized approach – OvuFriend analyzes your symptoms and statistics in the context of your unique cycle, recognizing that every woman is different and needs an individualized plan.

Thanks to this approach, OvuFriend can accurately pinpoint your fertile window and ovulation day, help detect possible hormonal or fertility issues early, and provide personalized diet and lifestyle recommendations.

That’s why OvuFriend is trusted by over 100,000 women who successfully conceived using the app – making it a reliable companion on the journey to pregnancy.

What do I need to get started with OvuFriend?

Nothing complicated — just download the free OvuFriend app from the App Store or Google Play and start logging simple daily notes about your body, mood, or activity.
Want to go deeper? You can also track your basal body temperature (BBT) each morning with a thermometer that measures to two decimal places — but it’s totally optional. OvuFriend can still accurately predict your ovulation and fertile days without it.

Does it make sense to use a menstrual calendar if the cycles are irregular?

Yes – this is especially important if your cycles are irregular. That’s when it’s the hardest to determine fertile days and ovulation on your own.

OvuFriend uses artificial intelligence and data analysis to predict ovulation and fertile days with over 94% accuracy – even with irregular cycles – and to detect potential hormonal issues.

Perfect 28-day cycles with ovulation on day 14 are actually rare – that’s why logging your data regularly in the app is key to understanding your body and increasing your chances of getting pregnant.

What disorders can be detected with the OvuFriend Ovulation calendar?

Information from the OvuFriend application will help you to detect such health problems as:

- Hormonal disorders that result in deviations in the menstrual cycle - e.g. irregular cycles, too long or too short cycles, incorrect length of menstrual bleeding,

- No ovulation or temporary problems with ovulation (anovulatory cycles) - it is normal that from time to time every woman has cycles where no ovulation occurs (so-called anovulatory cycles). In case of a fully healthy woman, on average, there are about two such anovulatory cycles per year; there should be no more. If track your cycles in the OvuFriend application and the system does not determine your ovulation cycles, it is worth consulting a specialist who will probably have the cycle monitoring carried out by a gynecologist. 

- Late ovulation - it happens that ovulation occurs very late in your menstrual cycle. If this happens in your case, and your cycles are prolonged, it is worth consulting your doctor.

- Luteal phase disorder (short luteal phase) - occurs when the second phase of your menstrual cycle (from ovulation to the next period) is too short. The average luteal phase lasts from 10-16 days. If your second phase of the cycle is shorter and you are trying to get pregnant, it can make it difficult for the fertilized egg to implant into the uterus. 

- Endometriosis - your menstrual cycles may have symptoms that may indicate endometriosis, such as heavy, painful periods, pain during intercourse or abdominal pain accompanying different phases of your menstrual cycle. 

- PCOS (Polycystic Ovarian Syndrome) - a hormonal disorder common among women of reproductive age. It results in irregular periods or no periods at all, difficulty getting pregnant as a result of irregular ovulation or failure to ovulate, excessive hair growth (hirsutism) or weight gain.

- Thyroid diseases - hypothyroidism or hyperthyroidism. Thyroid diseases can affect your menstrual cycle. In combination with symptom analysis you can detect a deviation in your thyroid gland at an early stage. Thyroid diseases impair fertility and can even lead to miscarriages. 

- Low levels of progesterone - low levels of progesterone in the second phase of the cycle may indicate lower temperatures from ovulation to the next menstruation. By measuring your body basal temperature every day and observing your fertility, you are able to catch problems with low levels of progesterone. Interpretations of the temperature level can be found in the OvuFriend Fertility and Health Analyses, the system will notify you if it detects any abnormalities.

Other abnormalities in menstrual cycles, such as recurring pain or spotting. See the section "Consult your doctor" in the application and check if you have any parameters that are worth consulting with a specialist.

Remember, although we use the most advanced machine learning algorithms and the latest expert knowledge to interpret your fertility and menstrual cycles, OvuFriend is not a diagnostic and medical tool and under no circumstances can it replace medical consultation and reliable medical diagnosis! OvuFriend is only supposed to help you to take care of your health at home, achieve your goal (e.g. get pregnant), or help you to catch at an early stage possible problems that you wouldn't be able to detect before a long time without your proper attention and awareness, and our analysis.
