Concerned bump, help/advice please.

i had a new partner at the beginning of January. toward the beginning of Feb, i noticed a hard pimple like bump, went away within 1.5 weeks, with no issues so i didn’t think much of it .

I had another singular bump come up recently (pics is of current situation). it was hard to the touch like there was build up or something under the skin. only hurt when i tried to squeeze it and investigate it. no other noticeable bumps around it. it actually popped overnight, so i’m not sure if me messing with the bump has caused more of an issue.

the only change i’ve had in life is working 2 jobs now. i don’t take a shower as often (was showering one a day or every other day, now its either every other day or every 3rd day…) could this be causing pimples in my vaginal area? or does this more reassemble an STD and i should go to the doctor?
