Did I Have a Miscarriage??

Patient: My boyfriend came inside me and I was not on birth control. I took plan B 48 hours after. A week later I had some bloating and I started bleeding very lightly.. the light bleeding lasted over a week. which made me think it was my period and that the pill had worked. Then 3 weeks after that my breasts got swollen and very very tender.. I was feeing very tired and having lots of crazy dreams. I was hungry.. feeling bloated, gassy, and having to pee alot more than normal.. I had some nausea too., and was very emotional. These symptoms lasted probably 2 weeks but then I got my period. But this was ALOT heavier than my normal periods.Do you think I was pregnant,and I had a miscarriage?
