Anyone experienced this 16 weeks pregnant?

I am 16 weeks pregnant and have this pop up. It’s right where your underwear falls kinda in the crease between your outer lips and thigh but low down near the hole. It doesn’t hurt unless I touch it, no itching or soreness... there’s just one. Not sure what to make of it! I’ve attached two pics just in diff lighting. Has anyone had similar before? Sorry for the hair 😩😂
