Had sex this morning at the baby moved to just my right side my tummy looked uneven, is he okay? 35 weeks pregnant.

He's perfectly fine. Babies can still move from one side to the other at 35 weeks. As long as you're not leaking fluid, having strong persistent cramps, and have normal fetal movements, don't worry. You did nothing wrong and it's perfectly ok to have sex in your 3rd trimester.
