33 weeks pregnant with irritation to perineum

Hey guys I’m wondering if any of you have experienced this... I am 33 weeks along. The last two weeks I have had an insane amount of discharge so I’ve been wearing a panty liner. I know, probably won’t help my case. Well starting a week ago the only discomfort I have had was on my perineum and around my anus. I assumed it was from the moisture from wearing a pad and the discharge and then everything rubbing down there. I got really itchy only in that area (no where else on my vag) and I rubbed so much with toilet paper until it stung 🤦🏼‍♀️ I took a mirror and tried to look and saw three red spots and freaked. Now I trust my husband 100% and we have been together for years. The only other thing I could think of was I tried to shave with a full razor in a hurry and did get razor burn down there but didn’t think that would be related to my perineum now itching and burning with the red dots. Could it be from the discharge? Ingrown hairs? I’m waiting for my dr to open up so I can call but that’s 3 days away. I also lost part of my mucus plug a few hours ago so now there’s that as well 😅 I’m trying really hard not to think the worst but of course that’s where my mind goes. Please tell me there’s other possibilities to what this could be because google keeps saying herpes and I know my husband and there’s no chance for that. The discharge doesn’t itch or burn either it’s just annoying and the only irritated place is my perineum and I just want relief.
