Ok so my period was due at the beginning of the month according to another app I use and now it says my 21 days late but <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> says I'm not due till around Halloween, but somehow I didn't notice that I never had a period in September either but I had 2 in July and my August one was super light to the point when I accidently left my cup in longer than 8 hours it was still pretty empty. I had safe sex (extremely, to put it politely he finished on my boobs) so I know pregnancy isn't on the cards (thank god) butsomething at the back of my mind is telling me somethings wrong. Any advice ladies?
