Not feeling sexy

This is my least favorite part of pregnancy, I forgot that I felt the same way with the first baby. I feel like a whale and don’t feel attractive at all. My fiancé thinks I’m super sexy and can’t keep his hands off me (no more than usual lol) but I just don’t feel it. I’m not interested in sex because I don’t feel attractive. How do I get over this? Nearly 30 weeks and I feel miserable. This all started when mommy original OB called me fat when I was only 8weeks along. No GD or anything she just said I was fat.
