I'm 5 weeks 4 days today. I went to the bathroom and when I stood up there was a drop of blood in the toilet. When I wiped there was some red blood on the toilet paper. Not a huge amount and no clots. I went to the OBGYN last Monday for an ultra sound after going through two blood work to confirm pregnancy. It was too early to hear a heartbeat. But we saw the sack. It's Sunday so I have to wait to call my docotor tomorrow, so I'm calling out for help and support.
