A few weird "periods"

So I've obviously been tracking AF on this app, but it seemed to be off by about a week. I adjusted my dates on here in September (was supposed to come on the 27th) it came at the beginning of October and then I had another "period" mid October. I had no symptoms (no sore boobs, fatigue, breakouts or food cravings) I kinda just bled and that was it. Well now my nipples are crazy sore, I'm breaking out, eating everything in site and I'm way emotional. Could it be pregnancy or do y'all think my period is just out of its normal cycle? P.s. We had sex on all the days that glow said I was ovulating and glow says my period should have started 3 days ago but it hasn't. Help!
