Yeast infection/ BV

I have never had BV before but I have had a yeast infection it’s been a while so I forgot what it really felt like I just remember having a lot of clumpy like discharge not really a painful feeling I’m 33 weeks pregnant and I’ve been having vaginal discomfort like a painful feeling and it itches very bad not only inside of my vagina but along the lips as well there is discharge there but nothing out of the ordinary it’s normal discharge I’ve had my whole pregnancy I’m wondering if is this pregnancy related or could it be BV or a yeast infection due to the pain I do have an appointment scheduled tomorrow but I’m just wondering has anyone else experienced this I have not been sexually active this whole time so it’s not an STD I’m clear of those but is this a normal symptom this is my first pregnancy going this far
