I don't know that my nips were swollen, but the did seem to protrude a little more and got hard really easy bc they were so sensitive. Now my entire boob hurts, not just the nip lol I haven't really had cramping since the week after AF was due, but I've heard it's pretty normal bc your uterus is stretching.
I have to try not to roll over or stand up too quickly or it feels like I pull stomach muscles!
