My doctor diagnosed me with a low lying placenta at my 20 week scan last week. She says 2 months with no sex, not even an orgasm. I haven't had any bleeding at all, but its still a bummer :/

Has anyone had this diagnosed in a previous pregnancy and the placenta ended up moving up as their uterus grew? I'm nervous it won't move and I will have to have a mandatory c-section. They will check the placement in January at my 28 week scan to see where it is lying.
