Take a few deep breaths. I totally understand your anger, confusion & worry. Totally. I have my own issues & problems getting help for them. But let's see if we can sort your worry out ! X
it appears that the StrepB shouldn't be causing your symptoms, It also appears not to be an issue having it in your body, other than needing antibiotics when you deliver your baby (congratulations on your pregnancy!!).
you've ruled out thrush & BV, I know you said it won't be STI, but if I were you, I'd get a full check, I'd just book privately & get it done.
Have you been checked for diabetes??
your description is exactly what I get when my blood sugars are too high. (I'm diet controlled but occasionally behave like a twat and eat like a normal person, or worse!! 🙄).
TMI maybe, but I relieve the symptoms, by using the wipes called 'water wipes' none of the others. Wipe everywhere and then lay one length wise between your labia & leave it there. It works wonders.
best of luck getting or sorted!!
