Possibly. Every body is different.
I'm 38 wks and "doggy style" is easiest. Nice thing is that positions that may not have been comfy b4 are better now since things move around and change down there. So you may revisit some that didn't work b4 u got preg.
I'm almost 38 weeks, and it seems like it hurts everytime we have sex, and for a little bit after. It's reeaaaaalllly hard for us to find a position that doesn't hurt.. TMI but, Doggy seems to be the only one that doesn't hurt AS bad as the rest of them.
