Plan b question

Hi guys, first time taking plan b and it was october 8, roughly 22 hours after the deed, he did not finish inside, bit i’m scared there might be precum (he had no condom despite me asking him to use one). I’ve had withdrawal bleeding, on and off vomitting sensation without actually vomitting, clear to cloudy stretchy slippery discharge that turned lotion like white, sticky discharge to just wet discharge to very small amount of white small clump that can be stretched a bit.

Still waiting for my period, i’ve done a few tests starting from october 21 until 29, then very recently november 3 and all were negative. I guess my question is did anyone here who used plan b had the same symptoms?? why is my discharge taking too long to settle and why is it back to the small clump of slightly stretchy discharge?? can i trust all my test results?? pls someone help me
