Learned my lesson

Danielle • Mommy to a precious little boy born 12/17/15 and full time working mom! I love my little family!
I went to a huge consignment sale last night for new mom/dad day. They opened the doors at 7pm and I had to be in line before 6. I didn't leave until after 930. It was a concrete floor and lots of walking/standing. I had THE WORST pelvic pain I have ever had in my life last night. I couldn't even roll over on bed or put on my pajama pants. I could feel baby moving around and I knew he was fine but I was hurting so bad. I think it's safe to say, at almost 26 weeks, I won't be doing that again. 
Has anyone else been suffering from intense pelvic pain after walking/standing for a while?
