vaginapagina | Lack of Periods and Smears.

Hello, ladies.

I've been thinking about perhaps getting a pap smear soon, however I'm 19 and I'm not sure if there's a limit on how young you can be to have one? I read the FAQ but maybe I missed it, I gathered you had to be at least 21?

Anyway, I've always had trouble with my periods, when they first started (age 13), they were very heavy and painful and irregular, I then lost them for 1.5 years due to eating issues, then I got better and they came back the same way as they started, except heavier. Now, for the past two years, they have been coming and going very much sporadically, I maybe get 3-4 periods a year (if that), my last period was only 4-5 months ago, but I'd like to get some tests done so I can fix this, as I don't want to risk my fertility (if possible).

Does anyone know what this could even be/is a sign of?
Any experiences would be extremely helpful, thanks. ♥

ETA: I've been on four different types of "the pill" to try and regulate my period, and nothing has worked.
