I have been up for the last 4 hours with what I think are contractions. I have had period like cramping with pain in my back and down my leg at intervals of about 5 minutes apart. I have no other symptoms though. No bloody show, no amniotic fluid leaking, not even discharge really. I called my doctor and she said to drink fluids and if it gets worse to go to the hospital. It hasn't gotten worse but I'm definitely still having them. I don't think they're Braxton hicks because they don't go away if I change positions and are not inconsistent. Has anyone experienced this before?
