Hi, I'm very confused. My cycle is usually 31-34 days long, but this month, my period started on Day 26 (Sunday). Which never happens. I actually thought it was an implantation bleed to start with (although I didn't have this with my first pregnancy), but it got heavier. It is lighter than a normal period is for me though, and I havent had the back pain I usually get, just a dragging feeling in my abdomen, which has actually gone now. I'm still bleeding today. My boobs are also more sensitive and slightly bigger than normal. So, I can't be pregnant, can I? Would POAS be silly?
