Stressing about my late period.

Im on a 28 day pack and im halfway through the last week of “reminder” pills.

I still havnt had my period and i take it consistently, i literally obsess.

Im really stressed out and now im stressing about my period. I usually only start it on the second or third reminder pill but ive only been on the pills for four months. I wasnt very consistent at all before i was on birth control.

My boyfriend and i have been having unprotected sex for a month or so now. We dont use condoms, he pulls out (i know that’s ineffective).

I read in my birth control instructions that its 99% effective.

Hoping to hear some comfort because i really am stressing alot lately.

But i dont know any symptoms of pregnancy whatsoever.

Update: i woke up today to my period! Oh

I would still like to hear tips on this issue if anyone has any.
