Morning after pill help and advice. 🤦‍♀️

So I had to take the morning after pill 2.11.18. After having sex and the condom splitting in half! We’re not trying due to a mmc in April and wanting to give our body’s a break. But we also aren’t on birth control because it messed with my body so much it took ages to come out of my system. Anyway. I had very dark (oldish coloured) blood over the next few days which started 13.11.18 (4days) which is my average period phase. Is this classed as my normal period that came early? Last period before taking the morning after pill was... 23-10-18. (4days) but I’m now a day late for my normal period. So don’t know which one to believe. My bleeding I had after taking map or the one I’m still waiting for??
