I'm 34 weeks and literally just went in yesterday for contractions and some leakage. They felt like menstural cramps in my lower back. I thought it was the real thing! But I guess they were just small ones and they were normal the nurse said just because I'm getting contractions doesn't mean he will come sooner than expected!
BUT I called my doctor right away and he sent me to labor and delivery so to be safe I'd call :)
