Sex.... 38 Weeks & 1 day (mature ppl pls)

Natalie31o
I'm a first time mommy, and I just wanted to know if it's bad if my husband and I are still having sex since I'm 38 weeks & 1 day. I feel kind of embarrassed to ask my doctor. When is the best time to stop. Or if I shouldn't be having sex anymore??
I still enjoy having sex, I haven't experienced any pain. But I have noticed that when we're done.. 
My baby starts to kick and moving around
