So I had some brown bleeding this last few days, very little. When I woke up this morning I was having the same kind of brown bleeding but a bit heavier (I'm only 4 weeks). Being concerned, I went and talked to my OBGYN. She did a pelvic exam only to have some red blood once she felt around my uterus, and also discovered my uterus wasn't fully closed. She told me I am having a threatening miscarriage. The baby is ok at the moment but I am now on bed rest until further notice. I go for an ultrasound on the 30th but it's so hard to keep myself together until I know what's happening for sure. This is my first pregnancy, and I'm so scared I'm going to lose this baby.
