Talk to Gynecologist on Wecondary Infertility

I concieved my first baby spontanously after marriage who is almost 3 years trying to concieve again for last 9 months but its not been to my gyne and she said to get a tvs pelvis done... Is k illawa insulin test and prolactin too both the test were normal but my ultrasound shows the follicles were 0.5cm on 8th day of ne lezra ka course suggest kia hai puchna ye hai k kya pcos k patients k liye ye effective hai aur kitne chances hain concieve krne k because i have heard k pcos k liye diabetes ki medicine di jati hai but she told me to take lezra and presage after that
