I miscarried 13 days ago at just over 8 weeks. My bleeding stopped a few days ago.

I normally use Clearblue digital opk and initially I was getting peaks due to the pregnancy hormones. Yesterday I finally got low fertility and today I got flashing smiley, high fertility.

For this month I’m also using cheapie opks as a backup and this morning the test line was so faint it was barely there. It was lighter than the one I did yesterday.

How can they be doing opposite things? Clearblue showing closer to ovulation but the cheapies showing further from it?
