Ovulation timing

Okay so you get your positive LH surge for ovulation and it last a couple of days and goes back down. Is it possible that you could ovulate at a different time? Like for example I got a positive surge for a few days last week but is it possible that even though I’m getting negatives im ovulating now? Seems confusing. I’m just freaking out in my mind during this two weeks wait😂 I want my rainbow baby sooo bad💜
