I think I am having another chemical pregnancy. Sunday my digital test read 1-2 weeks pregnant. Monday I was spotting a bit and got my blood drawn. I saw the results this am and they were 8. And more spotting.

I ovulated January 25. I should be 4 weeks 1 day. (Or just over two weeks gestation)

This was spotting from yesterday. It’s different today and darker.
