Quit bc pills..had period..this month no period..I'm lost?

So I was on yasmin for 2 yrs.. then I switched to yaz 3 months ago.. (hated it gave me migranes) I quit bc pills and my period started normally when I quit that month(last month). Well me an dmy bf have been ually active since then still, and my period was due 5 days ago, but not here... I have cramps and ALOT of discharge..but no period. Anyone experienced this and was pregnant? Before my period was due I started getting symptoms like pregnancy nips hurting.. and now since I'm late they don't hurt but my bbs are a little fuller and sore on and off...but still no period...
