My gf is 15 weeks pregnant and doesn’t want to have sex or anything is that normal the whole pregnancy she never wants to have sex nomore?

Yes, it's normal. She has a lot of hormones running through her, and it often makes women feel ill or simply adverse to being touched.

many dont want sex after the baby is norn

Yeah, maybe she feels uncomfortable to have sex thinking that she has a baby inside her or maybe she’s tired by the pregnancy. All you can do is talk to her and understand her reasons and see if y’all can solve it together
