So about 6 months ago I experienced a blighted ovem... which has made me paranoid to no end about getting pregnant. But I've been spotting this brown stuff like old blood for the past week, I am hoping its implantation bleeding, but today I started cramping pretty badly and have started to bleed a bit. I haven't taken a test, honestly a bit scared too. Before the blighted ovem I had a miscarriage. What should I do?
