I haven't had any intercourse since 10th of last month


I ve had my regular period on 22th(it was 4-5 days late as I was too
freaked out with the thoughts of "Am I pregnant?I don't wanna be!"etc.) and I had protected sex(condom) on 27th.

Yesterday I saw two little brown spots on my pantyliners.No spots since then, so I wonder if they are implantation spots,ovulation spots or just the leftovers from my period?
