2 days late +OPK/-hpt

AF is 2 days late. I last took an HPT the day of my expected period and it was negative. I also took an OPK and that was positive but not blazingly positive (see pic). I have a long LP so I’m guessing that’s why, if I am pregnant, the HPTs are still negative even though AF is late. But the positive OPK is throwing me off. Aren’t HPTs more sensitive than OPKs? Could the +OPK/-HPT be a sign that the pregnancy just didn’t “stick”? For background, I got a positive OPK the day I found out I was pregnant with my first, but I also got a positive HPT at that time. Curious to hear if anyone has had anything similar happen. Plan to test with an HPT again tomorrow morning.
