implantation bleeding??? sorry if this is the wrong group

i started to have light pink discharge on dec 28th i had sex dec 20 and the condom broke!!... 3 fucking times yeah i’m unlucky i know 4th one was a charm but he did cum in the condom but he was still inside me so idk if it leaked i’m not sure.. but i am on the progesterone only pill and i accidentally missed a week but then was late for another week so in total 2 weeks not being protected... the discharge stopped for 2 days. i recently had protected sex yesterday and had light light bleeding?? i’m wondering if this could be a indicator that an embryo is burying inside of my uterine wall (google told me this lol).. also causing period cramps and me just feeling sick overall i really don’t know... i took a test around 4:30 am i could not sleep and it came out negative with a weird shadow pretty sure i didn’t pee on it long enough but when i put the x ray filter on it it showed a faint line?? i don’t trust that though at all so... its early for me to test i feel what if this all started later my friend who is a mother told me she bled like i did after sex and then she found out she was pregnant...

TMI WARNING AHEAD

this is what i have going on now... i never took a picture of the first sighting of pink discharge because i didn’t have my phone on me but yes this is what’s going on..

forgot to mention the i do not get my period in general even without birth control i have a absent period so it’s definitely not a period starting ugh
