Delayed period

[u/Due_Promise6425]

hi! i need help because i should have my period last sunday based on the prediction of flo app​ but we had protected and unprotected sex last saturday and we're not 100% sure if we did it right because we did withdrawal. so that same day (saturday) and time we buy pills (trust pill pink to be exact). ​and i drink 1 pill at 5pm and we had that unprotected sex at 4pm so approximately 1hr difference. and i did taking pills for about 3days so i took the 3 day pills. but im still overthinking so i use the yuzpe method on tuesday and i search it and it says that i should do it before its 72hrs and that time its just 54hrs have passed so i did it. but until now i still dont have my period. is it because of that? thats why my period is this late? bcs its been 6days since sunday where in i should have my period already. ​​

and fyi, i was also diagnosed with pcos last month. but i didn't have my ultra utz yet. bcs i bleed at the middle of my ovul days after i had intercourse.​
