I am 26 year old, female. Unmarried. My period is regular. But at the 1st day of my periods, I suffer from lower stomach pain. Before my periods stay for 6 to 7 days but from last few months my periods stop on the 4th day. Does it will cause any problem in my future means my pregnancy? and now a days a boil type is there in my vaginal opening and it pains a little bit while I walk. It gradually becomes large and slowly day by day it becomes small then again large. Is this a big problem? or nothing.
