early period or implantation bleeding?

[meggie89]

my period is usually every month on the 16th. it never varies. I expected that I ovulated mid towards the end of the month, I thought I felt it. I didn't have sex at all, but I saw my husband this weekend on the 9th we had sex. and all of a sudden today the 12th I have light spotting bleeding, and serious cramps. Is this implantation bleeding?

It would be too soon for implantation bleeding if you only DTD 3 days ago. Also if you didn't DTD around ovulation it's unlikely that you're pregnant.
