I found out today that I am preg, although I have felt that I am for a while. I had a bt done on friday, and my hcg was low, only 11. I only got a BFP today, so I assume my hcg went up a fair bit during that time. I am guessing that I am about 5 weeks, as I O'ed later than usual, by about a week, on the 12th of october, which puts me at 5 weeks tomorrow. About an hour ago I went to the toilet and when I wiped, there was some red blood mixed in with CM. I know it can be normal to bleed during early pregnancy, but i've already had two early losses, and I'm scared I will losses this one too I'm going to go to the doctors in the morning, and hopefully the bleeding doesn't get any worse. There aren't any clots or anything, but I am having cramps. Is this typical or should I be worried?
