Hi I have been trying to conceive for the past 1 year, this time I had spotting during the ovulation window as well and we had intercourse during the same time. Had an ultrasound, found out mild PCOS for which the doctor has given normoz and duphaston for hormonal imbalance. My period is due as my cycle is of 29 days and I get regular periods. This time I am just getting brown spotting that too for 1-2 hours for 2 days now but no period. I am feeling extremely fatigued and have mild cramps as well. Is this implantation bleeding or due to medication? Please advise.
