Implantion bleeding/pregnancy symptoms!

Kayla
Helloooo! I was wondering if this may've been a miscarriage or ib? I was over 2 wks late for my period, I finally got some cramping then for 2 1/2 days I bled ( the first day did resemble a bit of a miscarriage, but after it was spotting like.) My periods are usually 7-8 days long so this is NOT normal for me in any type of way. Anyways, I had sex around the time of my ovulation too, now I am actually showing signs of being 6-7 wks oreggers? (Cravings(major!), mood swings, nausea, dizzy, & bloated....not due for a period till January 16th if I do not get one I think that I'll test for pregnancy.
