You can try a few simple methods to increase your body's production of fertile mucus:

  • Drink plenty of water - dehydration is not conducive to mucus production. Try to drink around eight glasses of water a day, which will lower mucus alkalinity.
  • Take vitamin B6, 50 mg orally once a day throughout the whole cycle.
  • Eat a lot of carrots - they are rich in beta-carotene and vitamin A, and so can have a positive effect on the quantity and quality of cervical mucus.
  • Drink a flaxseed infusion - some believe it increases the production of fertile mucus.
  • Take evening primrose oil (only until ovulation occurs) - it may help increase your fertile mucus.

Additionally, some medications, such as antihistamines and certain drugs that treat infertility (e.g. Clomid, Progesterone), may inhibit the production of cervical mucus. If you notice a smaller amount of mucus when taking these medications, do talk to your doctor. Sometimes it's not the increase of fertile mucus, but its dilution that is helpful in becoming pregnant. A component that effectively dilutes the bodily fluid (including cervical mucus) is guaifenesin, commonly found in cough syrups like Robitussin.

If you're producing little mucus, try to plan intercourse as close to ovulation as possible, because when there is no fertile mucus, the sperm cannot survive long while waiting for the egg. If you don't notice fertile mucus for a few cycles, you should let your doctor know. He or she will be able to give you the best advice as to what to do and what might be causing the problem.
