I went 2 1/2 years ago 15 weeks pregnant. As it was my 2nd pregnancy I was already showing (that bumped just didn't waste anytime coming out!) and needed pregnancy clothes. I stayed away from SM, BTMR, RRC, ToT, MS, TT and I think I passed on Splash. I did go on the Safari, Kali and Goofy's (my DD really wanted to go on). I will say for the Safari, try to sit near the middle of the car. We were in the back and OMG was it super bumpy, I had to brace myself many times. Kali and Goofy's were just fine, no issues there. I wouldn't risk a roller coaster just in case. I felt I'd ridden them tons of time and as much as I loved them I knew I'd most likely get to ride them the next year.
