Congrats, we are also pregnant (about four months) and if memory serves me, one of our favorite positions by that point was her on her side, me on my knees with one of her legs wrapped around me. Not only did this help relieve the pressure on her (she is free to put pillows about anywhere that makes her comfortable), but it also allowed me to still get deep, thrusting strokes. As an added bonus, I got to enjoy her ass a lot! If you're in the seventh month and her OB/GYN hasn't told you NOT to have sex, there is no concern as far as hurting the baby. It may feel strange to get an elbow poking you in the side at just the wrong moment, but keep your sense of humor and just have fun! Remember she is probably feeling VERY insecure about her body, so make sure you tell her just how sexy and beautiful she is - I can't remember ever being more turned on by my wife than when she's pregnant! She doesn't understand it, but she knows I'm not lying by that crazy look in my eye! Sorry to write a book - again congrats, and if I encounter another position that works well for us, I'll be sure to pass it on!
