If it feels like the baby is about to come out of your vagina that's not good ! I would maybe see your doctor to be safe but running is ok while pregnant
In moderation and at a safe pace I may add
Hi there. Well, some women exercise their entire pregnancies including running. (jogging type of running). Maybe you did overexert yourself though (which trust me, if I broke into a sprint right now, I'd have aches and pains as it would shock my muscles and ligaments as they have NOT been running lately. :>)).
I had a lot of pressure in my vagina when in my third trimester. That is normal.
See how you feel and maybe it was just a bit much for you. If your gut tells you over the next 24 hours something is really wrong, then call your doctor. In theory, we should be able to run and not have a complication to pregnancy. Baby is well insulated in there. But no one can know here for sure that all is well to tell you that so get checked if you think something is not right.
