I need advice

I’m 38w today and I’m not sure what’s happening with my body lol. Yesterday I went to the doctor and they did a swab. When I got home, I went to the bathroom and noticed pink on the paper and then a little bit more pink the next time I went. I was very crampy in my uterus and back and just felt exhausted. After that, the pink went away. I don’t believe the pink tinge or the cramps were from the swab because it was very gentle and not invasive. The pink also wasn’t mucousy so I wasn’t sure what to think of it. Today I am not crampy but I seem to be leaking fluid and I’m not sure if it’s amniotic fluid or not. It has a different smell than anything I’ve smelled before. It’s not pungent at all, but I notice it’s there. I’m not sure what my body is doing. I don’t think I’m going into labor because I’m not cramping at all. What do you think I should do?
