Ovulating, or not yet?

Kate

Ok, on April 12 I miscarried. I was 8 weeks. Today I noticed a ton of egg white, stretchy cm. Here are my tests.

Last week I had my levels checked and they were at 149, but they’ve been dropping pretty fast. So I know I still have a little bit of hcg in my system, but is the LH test positive because of that, or positive because I’m ovulating? I noticed I’ve been having slight cramps too this week.
