I’ve been on the pill since June and i’ve been taking it regularly. After the first month i got my period right after i took the last pill (it was on a sunday and my period started monday night). but last month it started while i was on the 19th pill?? and this month i took the last one on Sunday and it’s been 2 days now but it hasn’t started yet? is this normal? i thought the pill was supposed to make it regular. should i consider this “late” or should i just wait?
