I'm 31 weeks and i have this dull lower back pain accompanied with groin pain and at the top of my inner thighs. It does not hurt internally but almost like externally I pulled a muscle. Is this normal? I really don't want to call the doctor for them to tell me I'm fine but I will if I need to. Baby is still moving just fine and I'm not having contractions unless that's why my back is hurting. The pain is not unbearable, but definitely there.
