I would definitely still go!! I found out I was pregnant 4 weeks before our last trip, and I was 9/10 weeks along when we went. My nausea was horrendous, and we had to cancel some great FP+ last minute, but we still had a fantastic time! I didn't ride anything that had a pregnancy warning. For rides I was unsure about, I asked CMs. I think the only "big" ride I wound up going on was Soarin'. I know a lot of women go on some of the other rides anyway...but I personally didn't feel comfortable with it. Even as a big fan of the rides, I didn't feel like our trip lacked anything or that I "missed out" at all. It wound up being a much more relaxing, laid back trip, and I enjoyed Disney in a totally new way for me.
I have to admit, I did feel a little sad inside walking passed 7DMT after waiting seemingly forever for it to open, and then having a FP+ and having to cancel it. There was a split moment where I contemplated going on it anyway, but I just reminded myself I would be back and that I would ride it the next time.
