Hello there 3rd trimester

Well, I've officially hit 28 weeks and made it to the third trimester. I have back aches like no other and I already am not sleeping well.
Oh! And I feel like I have to pee ALL THE TIME! Like today, I feel like I go and then 10 minutes later I have to go again. And Yesterday, I sneezed and I peed myself... Twice! Boo! Anyone else?
