It's perfectly fine, as you get bigger it gets uncomfortable so get it while you can :-)
Thanks a lot for your help guys.
Definitely go for it, or if it makes u feel better ask her doctor if everything is going normal there shouldn't be a problem.
Im 31 weeks and have sex almost daily with my husband so far so good. I was told by my doctor that having sex and semen from the babys father decreases the chance of a miscarriage in the first trimester since it exposes the mom to a steady supply of the fathers dna so her body doesnt reject the embryo/fetus. Unless you're wife is told otherwise by your doctor I say go for it.
You are free to mingle as much as you wish as long as her Dr said otherwise! :)
Go for it!! Unless her waters have broken(when baby's on its way out) there is nothing stopping u! Most woman want more of it during pregnancy
