blood I'm scared!!

So starting Friday I felt like I had to poop so I was pushing to go and I think I might of strained to hard because some red blood mixed with brown came out. Then it happened again on Saturday, but it was just brown. Well tonight again it happened, but it was brown mixed with red again. I've only taken pregnancy tests I'm still waiting for the results of my blood test. I want to call the late night number, but I'm not actually in their system yet as a pregnancy test until the results come back. I don't know what to do 😭
