The egg is released 14 days prior to the next expected menses. The egg has a life of 24 hours while the sperms are active for 3 days. Keeping this calculation in mind, you may plan your intercourses. Alternatively, you may go for ultrasonography ovulation monitoring. It will locate the day of your ovulation. Accordingly, you can plan your intercourse. If there is any problem is egg release, you will have to take medicines for induction of ovulation. If you are ovulating normally and regularly, and still fail to conceive even after fair due trial, you will have to look for the other two factors : tubal patency and semen quality. Hysterosalpingography and Laparoscopy can find out any tubal block and even the intrauterine factors also. Semen examination of husband will inform you about the quality and normalcy of the semen. If within 6 months of fair trial you fail to conceive, please report to the gynecologist or infertility consultant. Hope I have answered your query. Let me know if I can assist you further.
