Spotting

Hey, sorry for the TMI post, I’m needing some reassurance.

I’ve had 2 early ultrasounds and am measuring 7 weeks 4 days all lining up how it should be the. We have also heard the heartbeat twice the first time was 133 the second was 147.

Since Saturday I’ve had bleeding on and off. I got checked and everything is okay baby is still going strong. However this blood is scaring me, I haven’t had any cramping though.

My first official appointment with my OB is on Wednesday. Any thoughts?
