Im scared for my baby

I have had so many health issues this pregnancy, been put on countless prescriptions and have had an ongoing infection for months now that nothing helps. At this point Im constantly in lots of pain so I really wouldn't know if something is wrong. As long as baby is moving I feel like that means atleast he must be alright? I have a growth scan next week and Im just terrified. Im currently 32 weeks and really hoping both of us can find some way to make it through the next 8 weeks.
