Fever blister

Ok so my husband and I were having sex and he didn’t realize that his fever blister(he has be getting them since he was a kid when he gets stressed) by his lip wasn’t all the way gone and he decided to go down on me. At the time I didn’t think anything about it well guess what I now have that on my vagina. I am 32 years old I never thought something like this would happen to me. There are lots of things going through my head. If anyone has experience this that can help put my nerves at ease please help. I just keep thinking if I get pregnant will everything be ok...is breastfeeding still ok. My husband and I talked to my doctor earlier today but I was just so embarrassed and scared and mad at the same time I didn’t know what to do. I have been crying all day. It’s a big thing to me.
