I am trying to conceive since last October, took 3 cycles of Letrozole, ovulated but didn't conceive, periods are regular. After letrozole and ovulation induction injections I developed PCOS in right ovary, I ovulated from left ovary all 3 times. Fluid collection in shown in cul de sac of size 2.9*1cm. I took antibiotics with placentrex injections, still that fluid is there. Tubes are patent in HSG test.
