Is it the plan b?

Took a emergency pill june 11th (a

Month ago) had heavy bleeding 5 days later with clots which lasted 3-4 days. Experienced lots of weird feelings (bloating, back pain, tummy pain) and diarrhoea but the diarrhoea stopped.

My period is late by 12 days but me and my mum went to the doctor today and did a pregnancy test (negative) and a urine test (clear).

But today im having this sort of discharge in my pants

On all the other days i had discharge since the time i took the pill it hasn’t stopped (watery, white stringy, lotion like) its weird.

I’ve lost weight and my veins are showing alot more which is scaring me thats why i went to the doctors. But they said im average weight. My mum is taking me to the hospital to get blood tests in the week or so. But could it be linked to the pill? Why is there blood in my pants? Can someone help?!
