Help me

I am 28 and still a virgin and also naive with sex and the likes. Somehow my boyfriend and I got carried away and we had a romance. It was quite intense. We both grinded naked. However when he wanted to release he did on a piece of cloth.

This happened three days after my ovulation day. Ovulation day was feb 10th while this happened on feb 14th.

I miss my period and I am pretty scared. Are there chances I would be preggy. Please when is it okay to test.
