31 weeks and hard to get up and down..

Danielle • 33yo, first time mom and so excited for it all!! Married 10.03.2014 and we are over the moon about our Nov baby boy!
Just hit 31 weeks today!!! 
I've definitely slowed down a ton!! And am really feeling it. Getting in and out of bed is hard with a low platform bed. 
I get mini cramps and pulls sometimes too... I know it could be some rls but has anyone else felt the same things??
