plan b question

i took it the 11th, & on the 17th i started experiencing the brown spotting than it progressed to red blood like my period & than i had a few small blood clots like i usually get from my period.. & today is the 19th & i’m bleeding like a period & cramping! it’ll get light & grown to light & than back heavy & than brown & then it’ll get heavy again throughout the day! my actual period was supposed to come the 28th, so it was extremely early! but i know it says the pill can start your period early! but is THIS early normal? lol... 🤔 also my SO, literally never precums.. he didn’t cum at all & he literally never has precum & i know because i give him head all the time & i never taste it & never feel any come out, but with other bf’s i have tasted their precum before & felt it come out! so i feel like i took the pill for no reason basically & now it’s fucking me up, cause i have no appetite really & my mood swings are fricken nuts!!
