Help! Any advice greatly appreciated

Cynthia • Joseph Aaron Tapia 7/1/16 Baby #2 due 9/28/18
So I am currently 26 and 4 days. I've been lucky enough that my little one measures right on schedule. So as of late I've been having really mild cramps/pressure across my belly and in my lower back too. The first time was on Sunday and now today were it lasted pretty much all day. I've been to the emergency room and they said that although he has dropped and is in position, they aren't worried about him comming  early. My question is, has anyone else felt the pain I'm describing? It hurts so much that it's distracting me from my work and I'm pretty sure my boss is getting sick of it.. Any tips on how to aleviate the pain? I really don't like taking medicine if I can avoid it but if I have no choice then so be it.
