Hello lovely people!
I have been off the pill fully for two years,but on off for the other year.
I had a scan three years ago as had no periods and bad cramps.they said it looked like many cysts.
I am also worried having been cheated on with my first relationship and didn't find out till a while after feeling awful and bad cramps and a few signs that I had caught a Sti from this horrible person!
Do you think that could have potentially ruined my fertility?
1.i had blood work done-all normal
2.partners sperm all good.
I'm yet to be referred for next steps,could someone enlighten me on what may happen next and if you have a similar problem.im dying for someone give to work been with my man years! X
