So I have pcos with anovulatory cycles. And I literally spot every single day of the month. I've been taking metformin and myoinositol and thought I had a positive around 9 days ago. For the last 3 days I've had a constant lower back ache that feels like my ovaries are being tugged on. (If I could put it into words) lol. It doesnt hurt. It's just there. Lower back cramps were the first symptom I had with my last pregnancy over a year and a half ago but it sadly ended in a miscarriage at 7 weeks. I had a little bit of nausea but couldn't tell if that was all in my head or not. And my spotting has COMPLETELY stopped for the last 2 days which is definitely unusual. Has anyone experienced this??
