please help! pregnant or plan b symptoms?

K❤️
I will be getting a pregnancy test by the end of the week if I don't start, but just wanted to get opinions from others and see if anyone else has experienced this.
I feel like it's more than likely the plan b throwing my cycle out of order, but still nervous. 
Feb 8: had unprotected sex late that night (withdrawal method) 
My boyfriend didn't feel confident that we were safe though so he asked me if I'd feel comfortable taking plan b 
Feb 10: took plan b in the AM
Feb 16-Feb 24: spotting 
Feb 25: I think this was the day I started my period and this was also when I was scheduled to start my normal cycle (hard to tell because of the spotting I was experiencing the days before but heavier that day)
If this is correct start day, period ended early on 27th.
Fast forward to March 20: had sex again and was half way unprotected (stupid I know) then we put on a condom. Noticed very light pinkish spotting during sex but that's it.
Was supposed to start my period on March 21 if it was a normal cycle, but today is March 30 and I still haven't started. 
Sorry for being so detailed, but just wondering if I'm being really paranoid or not? Need some peace at mind.
Took plan b three years ago when we were irresponsible like we were this time and my symptoms weren't like they were this time. Only delayed my cycles by a couple days.
