i dont understand why am not geting pregnant.

Hello Elaine,
Welcome to ehealthforum,
What were the tests done for you? Did the semen analysis done for your partner look at all the variables as defined by WHO standard? A successful pregnancy depends on many factors (ovarian, uterine, hormonal, stress etc). You should consider getting a complete infertility work-up done for you and your partner to see if there are any underlying causes for the infertility/inability to conceive. Hormonal issues, problems involving ovaries and ovulation, uterine problems, cervical or vaginal infections should be ruled out for you. You might also need to have HSG test and hysteroscopy test done to rule out tubal blocks and also to rule out presence of uterine scarring. For your partner, semen analysis should be done to rule out infections and to confirm the quality and quantity of sperms produced. Treatment as needed (based on examination and investigations results) would be started to help you get pregnant. Consider visiting your gynecologist/obstetrician for further evaluation and assistance. Monitor follicle growth and ovulation using follicular scan combined with checking cervical mucus changes and the BBT (basal body temperature) charting to predict your ovulation and time your intercourse for having fruitful results. Have diet with foods rich in zinc content to ensure better maturation of egg and sperms. All the best.
Take care.
