blister/ sore

I just found out I'm pregnant but the inside of my vagina itches and I have 2 red sores/ bumps on my labia. I have never tested positive for any sti/std I've never even had a uti , except for now that I think I have a uti because of the itching but what can the sores be? I'm 6 weeks pregnant has anyone experienced this? the bumps only itch sometimes BTW I looked at pictures of herpes online and it looks nothing like herpes it looks like a red little ball it doesn't look like it has liquid or puss or anything inside
