Hello. My period ended on Jan 3rd, my boyfriend and I had sex on the 24th, on the morning of the 25th I woke up to a watery/mucusy, bloodstreaked discharge from my vagina. today (the 26th) I woke up to what looks like the begginings of a period, it was bright red with a bit of clotting which is normal. What could this mean? I am on Depo Provera, and it has messed up my cycle quite a bit.. (on period for 80 days straight, no period for three months etc.) Pregnant?
