Stopped taking my pills

Okay so in November I missed a pill and started my period the next day (normal for me) so I just stopped the whole pack and planned on starting a new pack when my period ended. Well I ended up just not starting my pills again and my boyfriend and I had unprotected sex on the 2nd the 7th and Christmas the 25th. I’ve taken two tests and both were very faint positive (first response) according to the app my period is 8 days late but the lines haven’t gotten any darker just super super faint. So my question is did any of you stop your pills and have a period that month and then not have it the next month? I had some brown discharge Christmas eve and then some pink spotting when I wiped on the 26th. But still no sign of my period
