positive opk and pregnant?

So I took a opk test today just for the heck of it and it came back extremely positive. I had a miscarriage very early (5 weeks but it had stopped growing at 4) and I thought I ovulated already however I know that after a miscarriage your cycle can be weird. I'm on my way to go and get a pregnancy test and take it in the morning. I've had some symptoms that I had previously( sore nipples and breasts nausea heartburn weird low cramps and moody and fatigue.) I was just wondering could the positive opk be a result of a positive pregnancy. Obviously I'll know in the morning but I'm curious.
