Help Me Analyze! 4wk 4 day goop

Li

Ok guys, I just got my BFP and I was really excited! I have my confirmation appt with the Dr this Wednesday. But what is this? It happened twice today going to the bathroom, but nothing since. I've also had some cramping. Help this was excited, but now nervous nelly out. Tell me something, anything! I've had positive FRER tests the last four days. I'm trying really hard not to stress. First timer here!
