I'm scared pls help

I had protected sex june 23rd and bc im paranoid i took a Take Action (store brand plan b). I looked at my period tracker later that night and saw i was due for ovulation like a couple days later. 6 days after I took Take Action I started bleeding and thought it was implantation bleeding for a couple days. Im scared bc I don't know if it was or not. Fast forward to around July 13th when I would have started my next period. I didn't get it. A week later I start having egg-white discharge. I figure thats normal. Now fast forward to today, august 15th and still no period, please someone help am I pregnant or not. I've taken 2 tests since my original skipped period and they came back negative so I'm nervous.
