Need help

I had a dream someone I knew was pregnant and last night .my dream scared the hell out of me I dreamed I was pregnant and  my stomach got bigger over the days I went to use the bathroom and I was using it at first and then I saw blood in the toilet and the baby I miscarried. I took the baby out of the toilet I was screaming and crying and when I woke up I was crying to. Today I'm cramping a little but I'm not pregnant as far as I know my period isn't due till June 1st last time I had sex was the 20th as my calendar on here says my fertile period just ended the day before but my calendar on babycenter says it ended on the 21st and my bf pulled out . 2 months ago I got 3 positive test and 1 negative but then my period came so I wonder if my dream is of fear or something. What does this mean? Any advice
