Hallow Dear Stench, Motherhood is every women natural instinct, and you are no exception to it. For pregnancy, mainly following factors are responsible:1. Woman has to release egg. This can be ascertained by different examinations and investigations. Though ovulation detection kit is available for domestic tests, the best way to go for ultrasonography. Daily scan for ovulation monitoring from day 9 onwards till ovulation occurs is very useful. Along with the evidence of ovulation, it gives information about the size of follicle and endometrial thickness at the time of ovulation. Follicles between 18 mm and 21 mm size discharge the healthiest ova. Endometrium between 9 mm and 14 mm is most conducive for implantation of fertilized ovum.2. Patency and normalcy of the Genital tract can be assessed by hysterosalpingography, Laparoscopy and Hysteroscopy. 3. Semen examination to find out the quality and the quantity of sperms and some other factors in the semen. So please to your Gynecologist and get these investigations done to find out the status of the normalcy of your fertility.  Since you are trying sincerely for 2 years for pregnancy, in vain; you need to get these evaluations done. Based on the reports of these investigations, further management can be planned. With these reports, you may ask me Direct question for further guidance.
