Space Mountain - no
Splash Mountain - no
BTMR - no
any others?
Officially, the speedway is the only other one that a warning. I don't think I'd be too worried about that one, but none of us like that ride so we skip it anyway.
Epcot
Mission Space - no
Test Track - no?

Maelstrom has a more gently worded warning; "Expectant mothers
may not wish to ride" rather than the "Expectant mothers
should not ride" that you'll find on the thrill rides. I rode it at 8 and 16 weeks pregnant without issue or discomfort. There's really nothing to it, I don't think it is any rougher than Pirates.

RNR - no
TT - no

Star Tours also has a warning, but I'm not sure the ride is rough enough to deserve it. Again, something I rode at 8 and 16 weeks pregnant. I'd advise steering clear if your stomach is at all uncertain, though; I was pretty much over morning sickness by my first pregnant trip at 16wks, but that ride was enough to make me queasy for about an hour. It never bothers me not pregnant, but pregnant, something about the motion turns my stomach. (Oddly enough, Mission Space:Green had no such effect
).
AK
EE - no
Safari - ?
others?
AK is actually the park with the most rides with warnings - Dinosaur, Kali River Rapids, and Primeval Whirl, in addition to EE and the safari.
I can definitely understand the warning on Dinosaur; I rode at 8 wks pregnant, but wouldn't have at any point once I was showing because you do get jostled around and the restraints can get uncomfortable. Kali is a little more gray area, but again I think the bouncing against the lap restraint would be uncomfortable for a woman who was showing even a little. Primeval Whirl I really can't say much about; I can't tolerate rides that are mainly spinning even when I'm not pregnant, so I've never tried it.
As far as the safari goes, I drive rougher roads on a fairly regular basis so I didn't hesitate to ride that one while pregnant. If it is safe enough for infants (there is no height restriction), I think it is a good bet that the pregnancy warning is strictly a CYA disclaimer.
