My husband doesn't want to have sex anymore.

Ever since we had our 12 week scan my husband just won't touch me. He says he doesn't want to hurt the baby 😒 
I really don't know what to tell him. I've explain that he won't even come near him/her. But he just says that he/she looks so comfterbale in there that he doesn't want bother him/her... My hormones are out of control!!! I've been so horny lately and he just won't give in 😭
