Hi I'm mary, i had unprotected sex and je ejeculated in me so i took plan b, I'm about 2 weeks late but about a week after my last period I bled kinda heavy for 4 days like a period. Since then I have been feeling kinda sick some mornings and very tired all the time. I haven't taken a pregnancy test Laitly but I did when I was a week late and it came out to be negative. Is there still a possibility I'm pregnant?
