Crazy strap on sex!

Me and my hubby enjoy lots of fun crazy sex and right before we got pregnant we bought a strap on to go wild with. We both really enjoy it, and I am wondering what thought are on using now. I told him he won't be using it on me now, just too much to handle lol, but I wanna still use it for him but I am a little worried because it sits around the lower pelvic area and I am 7 week now. 

Do you suppose it would be safe to give it to him, or too risky because of where it sits?
