NO PERIOD yet.. 5th day OF 7daybreak /sugar pill /combination on COMBINATION PILL

Hi i get my period all the time its almost never late my cycle is about every 24-30 days during the time i wasnt on the pill yet. Last year i went on the pill for a month (oct. - nov. ) and I got my period on the 3rd day into the sugar / placebo week. That was october - november i only used it for a month. I stopped taking it on december-january because me and my boyfriend and i werent seeing other.

Then last January 31 I got my period and started my pills AGAIN because i was going to be sexually active again.

I missed a pill on the 16th day, i was late for about 10 hours. So i took it and the other one for the day. My boyfriend came in me on the 16th day i was supposed to take a pill later that night but fell asleep early eveb though i had an alarm... 10hours late y'all hahah i read that there's a 12 hour window? But somewhere else I read it should be plus or minus 2 hours ONLY

Now 5 days into the week im supposed to get a period... I still dont have it... Im worried so please share your stories!!!

It's been 9 days since he came in me so im still waiting for 5 more days before i take a test.

Has this happened to you before??? What should i do if im not pregnant but didnt get my period? Should i change my pill?
