Hi and welcome to HCM. Ovulation generally occurs between day 10 and day 19 of the menstrual cycle, or 12 to 16 days. It is difficult for a women to know exact date of ovulation and signs of ovulation are not experienced by many women. Here are few signs of ovulation 1. During ovulation, the cervical mucus increases in volume and becomes thicker due to increased estrogen levels. It is often said that the cervical mucus resembles egg whites at a woman s most fertile point. 2.Ovulation may also lead to a 0.4 to 1.0 degree increase in basal body temperature, but difficult to determine this rise 3.Finally, ovulation predictor kits are available from drug stores (like i sure) that are able to detect the increase in luteinizing hormone (LH) in the urine just before ovulation. Most of the women who have regular cycles ovulate, but if you think that you are going through cycles without ovulation then its better to consult a gynecologist and she/he may suggest you a scan. A women said to be Infertile if she fails to become pregnant after 1 year of unprotected sexual intercourse, I suggest you to eat nutritious diet, Take Tab ovacare 0-1-0 for 3 months (it contains nutriernts which helps in ovulation) and observe for 3 months, if you fail to conceive its time to consult an expert. All the best Regards Dr Santosh
