7 days late period

Hello,
So I have a odd situation and I don't know if anyone has had anything similar. Me and my hubbie had unprotected sex on the 2nd. I took a ovulation test that day and it was very positive. This was also 2-3 days before my predicted period. I am now 7 days late on my period.
Is there a chance I'm pregnant? Or had anyone ever been in the same situation and what were the outcomes?
Thnx
