I haven't had any contractions whatsoever during my pregnancy, so I have no idea what they feel like. I just had a really, really intense cramp. I've had mild ones all day, but that one was far from mild

some people say they do. my friend didnt know she was in labor bc she thought she had to poop. baby was crowning by the time she realized it & got to the hospital.

Yes but a lot more painful and stronger!!

nope. it's a constant pain and super damn strong
