Can plan b one step still work for me?

The first day of my last period was on may 30th. Usually my periods last about 7 days and i almost always get my periods on time. If not then i get them about 3-4 days earlier. My next period is due on june 27th. Me and my boyfriend had sex on the morning of june 13th. our condom broke so we just decided to finish without it. after he came i cleaned up and he put on another condom and we had anal sex for about 15 minutes. I took plan b one step about 30-40 minutes after he came from the regular vaginal sex with plain water. On the 1st day I was a bit drowsy, weak and a bit dizzy at times I figured it was just the side effects of the pill. About 4 hours after I took the pill I got on and off headaches until I fell asleep that night. The next few days after that I got some light on and off cramping, increase in hunger, chunky vaginal fluid (which i've had many times before from dehydration so it may be that) been peeing a tiny bit more often and slight harmless headaches. I've also been crying very often but I guess that's just because I'm scared and not ready for a baby. I'm not sure if I was ovulating during the time I took the pill and I'm not sure if it matters since I took it so soon after. Right now i'm on my 6th day after taking plan b one step and this is all that has happened so far. I've been reading so much about this stuff on the internet over the pass few days and I would just like a straight answer with no judgements made. I could really use some clarification and help on this because it's all very scary and confusing. I don't want to get an abortion I just want this to work so I can start fresh and wait until I'm ready.
