If you take an ovulation test & it says you’re ovulating 2 days in a row (instead of the usual 1 day) are you likely to get pregnant with twins?

I’ve taken OPK before & only shown positive for 1 day. I learned today that I’m pregnant & know that when taking the ovulation test a few weeks ago, I got a clear positive 2 days in a row & tested around the same time so it was about 24 hours apart from each other. Has anyone had this happen to them? Does anyone know if I’m pregnant with twins?
