Could I be pregnant ?

I got off of my birth control pills recently. I stopped taking them after my last period and then just didn’t start my new pack. The day I ended my period I had what seemed to be EWCM and we had sex that day. Is there a chance that I ovulated right after stopping birth control? I have no clue when my next period will be since I’m not sure when my normal cycle will start so I don’t know when I should test. It has been 8 days since having the ewcm
