Ovulation test

Madison

I am on CD 13. Took clomid days 5-9. Now I am on Premarin 0.625 mg. I read where the clear blue digital tests for a change in your LH and estrogen. This might be a crazy question but would the estrogen pills give me the wrong reading on the digital tests? I got a high fertility today and I wasn’t sure if it was legitimate or a false reading.
