Could this mean I'm pregnant? PLEASE help.

Hi, my last period was on August 7, 2016 due to taking Plan B one step and I was supposed to get my period on September 6, 2016 and I still haven't gotten it. So far I'm 2 days late and I know that's pretty normal but I'm still nervous because I'm not trying to conceive. I've been feeling nauseous but no puking, mild cramps that come and go, headaches, and backaches. Usually when I get my period I have those symptoms along with sore nipples but this time around my nipples aren't sore. Right now I'm pretty dry with some watery clear discharge. I took a hpt on the day I was supposed to get my period and it came out negative. Today's August 8, 2016 and I'm going to take another but can anyone tell me what they think the problem might be? Pregnancy or could it be plan b messing up my cycle. Btw I know this was a dumb decision but my bf and I had sex AFTER the period I got from plan b BUT we had PROTECTED sex, we checked for holes there weren't any. Let me know what you girls think and experiences ? Please and thank you.

I am now 5 days late. Period like cramps, period like backache, and that's about it. No other symptoms.

I'm now 4 days late. Cramps feel like I'm getting on my period but it comes and goes, backaches, nausea but very little not as much as before, and headaches that come and go but aren't as bad as before.

Another negative hpt but still no period.
