I’m 38 weeks and last night me and the hubby had intercourse afterwards I started to have very light pink spotting and wasn’t to worried but when I used the bathroom again it was more of a red color by 2am the bleeding/spotting was gone . I felt baby moving the whole time with spotting. I’m having a c section on Tuesday and see my ob tomorrow morning, should I be worried about the spotting since it’s gone . No contractions
