Hello, I have irregular periods. I have got my LH and FSH checked. My lh is 22 and FSH is 6.9. I took Femilon tablet advised by my doctor for 21 days. and get my LH again checked on 3 day. When i got it checked it was 15, then again i was advied to continue the tablet for another 21 days. On day 3 it was the same. It ws around 14 and again the next month after taking the tablet, i checked it was 16. It had no impact at all. I want to get pregnant. What could be the reason. What should i do.
