Suggest New Sex Positions while Pregnant

Angela • We're happy & learning new things together as a family. Over 4 weeks & it's a completely new life experience for us. I'm happy to have an amazing support system from our family & friends.
So being 18+ weeks it getting slightly difficult having sex in our favorite positions. So I'm wondering besides missionary, me on top, and doggy style, are there any other positions to try that anyone can suggest?? Thank you!
