Almost positive opk?! 5 days after “mature follicles”

So 5 days ago my follicles were at 21mm and 20mm. My gynecologist told me to test with opks and that they both look ovulatory and I should expect ovulation to happen in 48 hours. It’s now 5 days later and I’ve gotten this, pretty sure when I test in 4 hours it will be positive since that was a BIG difference from lasts nights test. Are my follicles for sure going to be way too mature? Or do they slow down after they’re already mature? I’m so worried if they’re growing at 1-2mm per day they’re both going to be like 30-34mm by the time they release….im so down in the dumps. When she gave me the good news that I had the 2 mature I cried happy tears as I’ve never had any actually mature follicles let alone 2 mature…please give me some hope.
