Brownish pink discharge and spotting brownish blood a week after period?

Sh
I had my period last Sunday and it lasted until the 12th. I had unprotected sex in which my husband came in me on Friday, Saturday, and Sunday. And the weekend before that as well, in fact we were having sex on the 9th and after we were done I noticed I was bleeding and it lasted until the 12th. I had a dream that I took a pregnancy test and it was positive and everything in the room was bright pink and there were lots of disco balls and plants in the room. I took two pregnancy tests today but I'm on cycle day 14 so I think I should wait a little bit before testing again. I'm experiencing mild cramps that come and go instantly, lots of nausea, intense sense of smell, headaches, and fatigue. Before I schedule a doctors appointment, I wanted to know if anyone else had a similar experience.
