Awaiting results

So here's my story, and I'm wondering if I can get advice on what everyone thinks.

I noticed a red lump on my bikini line near my vagina. At first I just thought ingrown hair, but after a week it hadn't gone away. It wasn't overly painful, and didn't change in size/appearance. It hasn't blistered or anything, it's uncomfortable but not painful. I sent pics to my ex (still friends) who's thinks ingrown hair. We were together for 7 months having unprotected sex, and he never had any symptoms or anything.

I went and saw a nurse who said it could be herpes, but it didn't look like it. But she also didn't think it looked like an ingrown hair either. She swabbed it and I get results back tomorrow. She said because it's not an open sore she might not even be able to get enough sample to pick up an infection. I already have HSV1 because I get cold sores on my lips occasionally, so she said if it's positive it will most likely be HSV1 on my genitals, which is nothing to worry about, and I'll probably never get another sore again. She said you don't even need to disclose to sexual partners - which doesn't seem right to me but anyway.

Now I've been SO stressed out about this. The guy I just started seeing told me if it's positive that it's a deal breaker, which has totally crushed me. I guess I'm just wondering if anyone gets symptoms like that? Doesn't really look like herpes, it's a red bump, kind of looks like a blister but it has absolutely nothing in it. Isn't changing size or anything. My ex swears he can see a hair under the skin but I can't at all and don't want to mess with it (for obvious reasons) and it's been 2 weeks now of the exact same thing.
Please give me some reassurance 🙏
