Pregnancy scare

Amaree

Hey guys I’m 17, my last dates period was on January 26-31 and my cycle is normally 33 days. My partner ejaculated in me on the 15th, I believe these were one of my fertile days. But I’m 2 days late and I took a pregnancy test yesterday and I was negative. And last night when I went to wipe there was a pink discharge.

Could I be pregnant?? Help me plz
