What are the signs to watch out for? I just had a positive hpt sunday which would have put me at 5 weeks today. I started spotting brown saturday evening before I tested. Yesterday (Monday) I started cramping like I was starting my period. The pain got so severe that I was doubled over. I had pain in my lower back that felt like what I would imagine being stabbed would feel like. The brown spotting turned bright red. I had such bad cramps all night that I couldn't sleep. This morning when I went to the bathroom I had a lot of clotting and dark red discharge. Later this morning I passed a.big, stringy grayish pink clot and more smaller gray/pink clots and had massive cramps. I'm still bleeding but the cramps aren't as bad. I also had a very bad headache sunday and monday.
