In Aug. of 2006 I had a abortion in Feb. 2007 I got on the depo shot to prevent pregnancy. I was supposed to go back in the end of April/ beging of May.Ever since then my boyfriend and I have been having unpretected sex (for about a month) and recently i've been feeling some of the same simptoms as i did when i was pregnet last year. Is it possible that i could be pregnet?
