abnormal uterine bleeding
"On my second month. Just starting to get spotty (panty liner is enough) but nothing that isn't manageable. The first 2 weeks I had minor headaches and nausea but it went away. Very tender breasts, still. So far month one--no period. Yay.  Great not to have a period but if the spotting gets worse (I think it may) that kind of defeats the whole purpose long term. I'm using this to stop periods while training for a half marathon. So for it's purpose for now, I'm fine. As far as sexual activity, it would be uncomfortable because the spotting is dark and slimy and weird. But that's not an issue now....  So pros and cons. But no period 3 months in a row (hopefully) , that's all right my me!"
