Helpppp

I don't even know if I should post this in this group because it's about birth control but also about other things so sorry if it's off topic but I'm not erring any responses in any other group... So here's the story.  I took my birth control pill 3 hours late one day and it was the second pill in my pack and I wasn't sure what would happen so I was going to use condoms for the next 7 days to be on the safe side but on the 7th day before I took my 7th pill I had sex without a condom twice. I took my 7th pill a few hours later at normal time but just to be extra safe I took Ella the EC pill the next day. That was yesterday and I was having very mild cramps today which are listed in the side effects of Ella but then I started to bleed and that's not a side effect and it's not that much but sometimes the first day of my period is very light and I also have everything else that would point to a period, but I'm still on my light yellow pills and shouldn't get my period for 2 weeks. But also I'm scared because I thought you couldn't get a period without ovulating so if I was ovulating when I had sex without a condom then I could be pregnant but then I don't think I would get my period so I'm just so confused and scared so please if you have any response or any opinion please help
