Hey everyone. I'm 6 weeks 3 days today.  So I've been spotting on and off for about 2 weeks now. It's always been super light and in my cervical mucus. I went to the dr on Monday and we saw the baby and its heartbeat but the dr said it was too early to hear it. He gave me a rhogam shot because I'm RH negative. 
This morning I woke up and I went to the bathroom, when I wiped the tissue was pink and had no cervical mucus. The spotting stopped but I have no cervical mucus at all. I have another ultrasound on Monday. I'm trying really hard not to be concerned. I don't want to call my dr again because there is nothing he can do. I don't have any cramping, just super nauseous and having to go to the bathroom a lot. Does anyone have anything encouraging they can tell me?
