I am using a heating pad now... im not sure how to time I am a first time mom, and if I lay still it doesnt hurt but if I go to stand up it hurts really bad.
Sounds like back contractions. Try timing them an see how far apart they are. If the pain is to a point to where you can't bare it anymore I would call or have your husband/bf call an see what you can do. I know sometimes if I apply a heating pad it helps a little for me.
I would I ended up calling none due to back pain.. Told me hot baths, tylenol Max, heating pad
