Please help! Plan b and confusing symptoms

So i had unprotected sex 16 days ago on the second to last day of my period (25th Oct) and he pulled out before he ejaculated as he said he knows what it feels like leading up to it (tmi but his cum was all over the bed and none near me). I have shorter cycles of 22-24days, so ovulation starts to occur a few days after my period ends according to my app (I know the apps aren't 100%).

36 hours later on the Saturday I took 2 plan b pills due to being 80kg.

7 days later I started to bleed (enough to require pads but no where near as heavy as my periods), and in another forum they said it's the plan b hormones leaving my body (withdrawal). This lasted almost 5 days. I'm now 16 days past sex, took a pregnancy test yesterday which was negative, but I'm starting to have my usual ovulation-like cramps, sharp pains on my left lower abdomen, and my discharge is clear and stretchy, with the odd milky white.

Is it possible that now the "withdrawal bleeding" has occurred that I'm now ovulating a week later?? And that's meaning the plan b actually worked because I took it a couple days before I was due to ovulate which means it DID push my ovulation back??? As I know it can stop or delay.

Sorry for the long one, just freaking out...
