Am I pregnant?

29 dec day of intercourse. He came inside. Took plan b 2-3 hours after. I took a pregnancy test a week after that I thought was negative, and am overthinking that there is a line.

6-10 jan had supposed period. Something happened, and I got punched in the stomach. I bled the next day, which was really thick and clotty from 23-26 jan. haven’t had any bleeding since, but I’ve been craving lots of things, I’ve been sick for about two weeks and have weird

discharge since the day of intercourse. I’m really not too sure what to do, i will retest soon but I want to get others opinion.

-if all else, what explains the discharge that’s weird smelling?
