Couple days from 6 months pregnant and my vaginal are is being weird.

I`m discharging a lot more than ever before, around the uhm entrance is sore and feels dry sort of bumpy from the dryness.
Also at my place we`d been out of toilet paper and so I was using shirts or towels--dont judge-- maybe it just got irritated from the clothing and it not being soft.
I don't understand the dryness, soreness or sometimes itchyness.
Need help on solutions cause I`m kind of scared to let my boyfriend touch me and stuff but also just want to knoee what could help.

You may have brought bacteria from the rectum to the vagina or urethra or both, and there is an infection. This is more likely if you wipe from back to front instead of wiping just at your rectum.
Only a doctor or clinic can test and give you antibiotics, if that's what it is. It could be any number of things.
