Used opks but no bbt

The last time we were able to have sex was 3 days before peak opk - so 4 days before expected ovulation

We had sex Friday about 10pm

I got my first positive opk at 10am Sunday morning with second morning urine

My husband had to go out of town so unfortunately that was our only chance

I had ewcm every day from 5 days before ovulation up until ovulation (again this is going off of opks so technically I can’t be 100% sure I even ovulated)

But I did also have my usual ovulation pain from the day of peak until the morning of ovulation day(I normally get pain when I ovulate)

Is there a chance at all? Or should I count myself out??
