awkward!!!

so I put a bag of clothes in a bag and I was going to donate them, and it was a day where I was washing all my clothes so I washed everything. I talked to my friend and told her and I offered for her and her friend to look through them, but this is so awkward but 2 pairs of underwear I put in there were old and I guess vaginas are acidic so they were stained white, and I was so embarrassed and I was like shit I swear I didn't know that could happen and now I'm having bad anxiety hoping the other clothes do not have that. what do I do? is this as awkward as I find it to be :(
