5 Days positive

I have gotten positive opk tests five days in a row. They’ve been negative before so I know it’s not a bad batch. I’d text around noon and then again in the evening. I’m pretty dang predictable when it comes to my cycle. I’m just so confused at when I would have ovulated. I did have sex the day before my first positive opk test and then again a day later and then two days later.

Has anyone else had this issue?

Edit: today I had the worst cramping for about a half hour. It felt like my period was back. So weird
