should I get a hpt? confusing

so these are my charts. I started opks 2 days after my last period ended. I tested for about 13 days and all were so faint so I gave up for a week n a half. so starting last Friday, my cd 26 I had a postive opk... cd 27, another positive I skipped some days in between bc I didn't want to waste them I only have a few left. so I tested another opk today and super positive with only a hour n half hold. I have 2 more opks to use , if you were me would you buy a frer? ovia changed my whole cycle when I started entering my postive opks, my period is due in the next couple days.
