OPK POST LOSS? please help

Christie • Mommy to an angel. 👼 🤰🏾 With my rainbow baby boy ❤️

I lost my baby on March 29th... And assumed the bleeding I had was the miscarriage and tissue passing. My cycle has been regular for years and my OB said there should be no lapse in my cycle... Here we are.. Almost a whole month later....no period. Took an opk just to have an idea of what is happening... And this is what I got. Opinions?
