text: is sex safe while pregnant ? if yes, upto which month. is any risk involved ?   sex is safe up until your water breaks!!!!  as you get bigger, you are gonna find that different positions are better. don't put undo pressure on the baby. him being on top is not a good idea.  there are always risks, but i was preg 4x's and i had sex all the way to the end, it's great exercise and keeps you in shape, made delivery easier too! ( i was back in my normal clothes the next day )
