Random bump on mons pubis

I did some sexual things with a guy (he did not insert it in me) and he didn't have a condom. I have ONE bump on my pubic area but no where near vagina. It is slightly raised and skin colored and I tried to see if anything would come out but it was just a small amount of clear fluid and blood. Should I be worried or not? It doesn't look like any type of STD and there is only one bump

Likely a pimple or something akin to eczema. If its a single bump I wouldn't be too worried about it. Hit it with some cortozone cream or triple antibiotic cream and check back in a couple days if it doesn't go away.

If the original poster is in the UK (and most other European countries I think), it isn't possible to get antibiotics without a prescription.  If it's just an ingrown hair or pimple though, then it will probably go away by itself.

Could it be an ingrown hair? Is it in an area you’ve shaved recently?

Triple anti biotic cream is over the counter. it's a fancy name for anti bacterial, itch ect.

 Polymyxin B Sulfate, Bacitracin Zinc, Neomycin Sulfate, Pramoxine HCI

Are you in the UK?  As far as I'm aware, you can't get it without a prescription in the UK as antibiotic use is much more restricted due to antibiotic-resistant bacteria taking hold (some hospitals have had big problems with MRSA and c diff).  It's available on eBay, though it's against their terms of use.
