I lost my mucus plug on Tuesday and now last night I felt like I was having real contractions and lower abdomen and lower back felt like period cramps and I was up all night super uncomfortable with 45 second contraction 30 minutes apart but now this morning I haven’t had any contractions but I do have cramping... i didn’t think it was Braxton-Hicks because they hurt worse and came from my back.. is it normal I haven’t had another one?
