I am now in my 2nd trimester and I have begun feeling weird pressure and pain in my vulva, specifically the top my vulva near the clitoris. Its heavy and throbbing and makes it uncomfortable to stand still for too long or sit in positions like cross legged. Is this normal? Googling reveals nothing because this pain isn't pelvic, it's more like the vulva itself, and a tiny bit of the vagina opening. And it's a throbbing heaviness. Should I be worried?
