I'm 32 +4 for the last two days I've been having really bad back pain I do have back problems which I'm taking a medication for but when I take the medicine it doesn't last as long as it usually does and the pain is pretty consistent I'm having some stronger than usual Braxton Hicks.. Also my lady part is hurting , like it took a beating ( which it didn't ) is this normal ? Because I'm scared I'm in preterm labor..
