blaming it on pregnancy

I blame everything on pregnancy. With that being said... 
what is this?? 
It doesn't feel like a pimple and it's somewhat hard, sort of like a wart? And it popped up just yesterday from what I remember. 
Whatever it is, could it be related to pregnancy? 
Never had it before.
Also, ignore the hair on my leg (super lazy lately, haven't shaved in like a week lol!) and the fact that I'm wearing my boyfriends boxers..
