Blood clot/bleeding

Hi everyone,

This is my first pregnancy and I’m 9+4 today.

I had a clot of blood on the toilet paper when I wiped and blood in the toilet about two days ago, and then I saw a little bit of blood this morning (red both times).

The color of the blood concerned me because it didn’t seem like spotting so I went to my OBGYN and she said everything looked fine, and she couldn’t figure out why I was bleeding.

Has this happened to anyone else before? I saw the baby’s heartbeat today but I’m still feeling nervous and worried.
