Need little advice.....

Right I am diabetic and am first time mum

I’m 35 weeks and 4 days and I seem to be loosing a lot of discharge and getting pains down there but my discharge is little smelly aswell could it be an infection or is it my body preparing for baby?! Only time I feel okay is in the bath I hate clothes on my body and always in pjs bottoms and sports bra getting so fed up now:(

Feeling a little down aswell because I can’t do a lot and feel bloody useless at anything.....
