Not Sure what to do?? confused about tests

Lelia
Hi 
I came off my period on Saturday... tested with my Ovulation Kit yesterday morning to get a peak fertility static smiley. This is 2 - 3 days after coming off my period and 6 days into my cycle. I thought the peak was VERY early and I could've missed it if I hasn't done the Ovulation test so I did a pregnancy test Tuesday night - positive. I did a clear Blue digital wednesday morning - positive 2-3 weeks! Is that even possible considering ive just come off my period! It wasnt spotting either it was like a normal period. I've had a little spot this morning and yesterday!! So so confused!!! Please help. Could it be a miscarriage?
