Plan B, bleeding 2 weeks later, pregnant??

Hi, I have been searching and searching on the internet for answers so I thought I would try here. I took plan b twice during one month, once on November 4th and then I got my period on November 8th for sure (I knew it was my period because It was my period time and I had all the symptoms and it lasted for 5 days) Then I had unprotected sex on the 19th and took my plan b within 24 hours. I think my fertile window started that day but it says that I should have been ovulating on the 22nd. About 6 days after plan b I got brown discharge and some light spotting, which then after a couple of days turned into bleeding that filled up my large sized tampons. Now it’s been about 2 weeks since I have taken plan b and I have bloating, cramping, I’m nauseous, and I have still been bleeding dark red blood that almost looks like a period on and off almost everyday. I am so worried that I could be pregnant because I have all the symptoms, but I am also bleeding and I don’t have sore breasts. I’m a little confused...any help?!?
