Bleeding

So I went on a date with a guy and this was our first date together. I figured out that my drink was spiked days later but that night we had sex several times. I’m not on birth control and he came in me several times. So the next morning I took plan b but a different brand. I’ve been bleeding ever since and that was 2 weeks ago. I’m about to start my period in 5 days. Is this normal? This is my first time ever taking the morning after pill. Please help!!!
