S.C.
I had this at 6 weeks with both my kids. My OB said, it's probably fine, don't worry about it with my first (his usual response--frustrating, but he has always been right). With my second, I did have pain, so I went in and the pain was due to an ovarian cyst, the bleeding due to a subchorionic hemorrage (bleeding where the placenta attaches to the uterus). I was told to take it easy and just wait. Everything ended up fine both times, but I was nervous as I bled lightly for about 5 days with my first and 7 with my second. I hope everything goes smoothly and you are able to relax a little (I know it's hard).
