Peita,
See if you can get another u/sound. It is really the only definitive way of knowing. I had spotting for weeks with my current pregnancy and everything is fine BUT I also lost two bubs last year and my cervix was closed and HCG levels up on both occasions as they were "missed miscarriages". Demand to get done whatever you need to be done in order for you to be satisfied and don't be embarrased-- that's one thing I've learned. TRY to focus on the fact that bleeding during pregnancy can be quite common and that usually everything is OK. I will be thinking of you and trust the outcome will be a good one, Hope xoxo
