The difference?

The past few days I have been walking around a lot going to the fair and to quite a few yard sales. And today I cleaned out room for nursery and then cleaned kitchen/ dishes. But I noticed after doing these things each day I get really bad pains in stomach like period cramps, back pains, inner thighs hurting, etc. But does this sound like BH or legit contractions? I could literally see them in my stomach today. Also, Im suppose to have my prenatal appt Monday and is this something I should mention this to my doctor? I never had these kind of pains with my DD that I can remember and I have no idea if its just normal or Im over doing it maybe.

Sorry if this is confusing, Im just in so much pain and looking for advice.
