Should I go to er??

Hey ladies! I just had surgery two weeks ago and I'm pregnant. I was going to try to wait until my first doc appointment, but that's 3 weeks away!! 😩 I'm worried about everything being ok? Anyone have surgery then find out they're pregnant? Also having cramps. So my question is, should I go to the emergency room and have everything checked out? Thanks and no nasty comments!!! 😊
