Constipation related sorry for TMI

So I’m nearly 16 weeks (first pregnancy) and I’m unbelievably constipated I’ve tried everything different foods even the meds to help me go are starting to not work and I’m getting a very bloated and painful stomach to the point it’s hard to sleep and it’s causing pressure and sharp pain in the vagina area any ideas as I’m just fed up with being in pain and feel so down because of it
