I'm a little worried right now because I just presumably have gotten my period again, even thought I last got it on October 20. This is the first time in years that I haven't been regular - By regular, I mean I usually get it every 28 days, with very little variability. I just noticed this 20 minutes ago, so it may be a one day thing? I really have no clue.
I'm really worried. I know it may not seem like a big deal... but any insight?
(A tiny bit of background: Last week was one of the most stressful weeks of my life, but now I feel very calm after I dealt with the problem.)
