I am trying to conceive and diagnosed with Pcos so I am taking letrozole 5 mg from Day 2 of period for 5 days. On 9th and 12th day I had follicular scan and on 12 day the follicle size was 23x20 so Doc gave HCG shot. On 27th day I notice few spot and thought my period started .on 28th n 29th day I noticed light spotting with no cramp and stopped completely. I have done
pregnancy test next day but it came negative. I have light breast pain. What could be the reason of light spotting, if I didn't conceive why I had light period ? M really confuse
