Last year, a hard, pea-sized lump that does not move appeared on my labia minora, at first I thought it could be a cyst and didn't think anymore of it. However it is has been a year now and it hasn't gone. And for 10 months, my menstural cycle has been all over the place, they were once completely regular and always on time, now they are irregular, I am sometimes 10+ days late and have even skipped a whole month on 2 occasions. And instead of lasting 3-5 days, they now continue for 10-12 days which is obviously much longer than I had ever been used to. I have bleeding in between periods and when I was sexually active last year, bleeding after intercourse. I have an appointment booked with my gp for next month but in the mean time wondered if anybody had experienced similar?
