So I'm 19 and have been prescribed Diane 35 for cysts at the ovaries (as far as I've understood). It's been two years, and by now I know my PMS signs pretty well. Obviously, my period starts about the forth day after dropping the pack, and I start a new pack on the third day. PMS are usually breast tenderness, abdominal pain, back ache, and mood swings. BUT it's supposed to come today and I so far feel absolutely nothing. I have so far never taken any pill on an exact time, always varied a couple of hours at most daily, sometimes its 8 pm sometimes its 1 am.
My period is never late, could I be pregnant?
