I went to WDW when I was seven months pregnant. I had a great time but did not ride too many rides. It was the first visit to WDW for my husband, my daughter, and myself so just enjoying all of the other features and watching my daughter enjoy them was enough for me. I will say that we are going back in two months - basically because I want to go again and experience some of the things I was limited from the first time. I would ask your OB/GYN what you can ride. I was told anything my daughter could ride-I could ride. I had to avoid any ride that went in circles (Mad Tea Party). I did not go on the safari ride because it was stated that it could induce early labor. My husband and daughter did it and said it was not that bad. I probably would have done it if I was not so far along. I do know someone that did all the rides at two months along and her son was fine. My personal opinion is that if riding a ride could hurt my child then I would not ride the ride. Your doctor can probably give you the best advice. You will most likely have to avoid the roller coasters. Have a great time and just plan to go again in a few years!
