I had the same thing too about 4 weeks ago when I found out I was pregnant.
It went away on its own
Never knew I'd relate to you guys! I had no idea what it was.
My advice - go to the doctors if you are really worried.
Or
I had 3 sitz baths a day and it helped to get the blood flowing down there since you are fully covered in water. Make sure the water is not really hot but not luke warm. Somewhere in the middle.
And do NOT try to squeeze it. Or touch it at all.. it will take longer to go away.
You can also try wearing loose pants that won't rub on the area.
