Noticed a brownish bump in my pubic area

i recently noticed a brownish small bump in my pubic area. I got tested for STD's about 3 weeks ago and came out negative on everything (HIV, herpes, HPV). i talked to my urologist and he said I should wait 2 weeks and see if it goes away but I dont know if I should be worried or not. I messed with it a little bit so it's kinda irritated

Any help or notes on what this could be? (I shaved after noticing it so it may not be an ingrown hair)

Other than messing with it you have taken the best approach possible with all that you have done.
The Urologist has given you the best advice possible - if this is going to be problematical it will develop further than it currently is - what is required is the time for it to develop, or cure itself.
