I am confused

So I spent a little extra on opks this month because my internet cheapie order didn't arrive till today and I only had a couple left from last order. I have been testing since Monday CD15 and have got a positive 3 days in a row... So confused as the cheap ones have never showed up this dark before, and even when comparing the 2 the cheapies aren't showing that I'm having a surge yet. We have been very active ;) but because my sleep is so out of whack I haven't been temping regularly so I don't know when or if I have ovulated yet. What are your thoughts ? Has this happened to any of you? SH is

complaining that he is tired lol.. Should we keep trying till the opks are negative? Or can I give him a rest? ☺️ Sorry for the ramble and blurry photo!
