what could this be ?

Tamara • Mommy to my 2 beautiful baby boys, Nathan Louis💙 born August 12, 2017 and Parker Joseph May 6, 2019❤️ My whole world😍
I started spotting on 8/24, but it had stopped 9/4.. it got more and more each day and I peed out the fetus on 8/28, but I had stopped completely on 9/4, so we had started trying again.... But now today I get this??? I had some red discharge yesterday too? I don't know if this could be from my pelvic exam that I had done a couple days ago, but not sure what to think. I got a pelvic exam and blood work done on Monday and my obgyn had called me the next day saying my numbers were back down to 0 and that they don't need anymore tests but then my family doctor still wanted more tests done.(not sure why) so tomorrow I'm getting an abdominal ultrasound and more bloodwork. Before I went to my follow up appointment after I had my miscarriage and after we started trying again, my obgyn had said to wait a few cycles, but we obviously didn't so what could this be?😕
