If you're under stress it's possible for that to effect when AF comes. However, if you're experiencing some pregnancy symptoms, I'd go ahead and get a test and use it in the morning.
you can definitely take a test tomorrow with first morning urine. that will give you a good idea of what's up. if you're only on your third inactive pill, you period shouldnt really be starting until today, or even tomorrow. don't freak out yet. if you've been active and the pill has always worked for you, you should be fine. if you took all your pills everyday on time, then you should really be fine.
I have one more question though.. I am having this like clear discharge stuff and I have had it before but it was usually like after periods does it happen before.. and what could be signs of pregnancy?
that's all you have for discharge right now? it doesnt mean your pregnant. I get that before my af comes too. if you're really anxious, hold your pee for 4 hours, go buy a first response early result, and test for pregnancy. signs of pregnancy are the same as pms, sore boobs, nausia, etc etc. I doubt you are pregnant, what pill are you taking!? Make sure you let us know how you make out okay!?
