hello,

i am 19yo. and i just recently found out that i am 2 months pregnant with my very first child.

well... about 4 months before i got pregnant, i started having this kind of dull, achy, throbbing pain on the inside of my vagina by the opening. it comes and goes at random times, and lasts for a bout half an hour each time. sometimes longer than that. but i dont know what is causing it. and since i got pregnant, the pain has been getting increasingly worse. i've been to the doctor to have it checked, but each time i go, they say that they cant find what is causing it. i am getting very worried about it because, i am only 7months away from giving birth. and if this is something very serious, i need to have it found and taken care of before i give birth. so that i can have a healthy baby.
so does ANYBODY have ANY suggestions as to what this strange pain could be from??? please help me
