Sharp stabbing pains in vagina?

I started having sharp stabbing pains in my vagina today. I am ttc and my lat period was june 9th... Chemical pregnancy. its too early for pregnancy symptoms if I do get a bfp this month though. I don't have any burning or itching just the pains. They have not ceased at all today... They last for a second and go away then come back like 3 seconds later. Any ideas???
