Multiple positive tests?! Can someone explain??

Beth

I have had 3-4 positive ovulation tests this month. The darkest most obvious test line I had that was actually darker than the control line was the 19th. Can I assume that was my actual ovulation date? If so, can I take a pregnancy test as early as the 30th? I have very irregular periods, on my second dose of Clomid, and had a miscarriage in Dec of 2017. We have been trying ever since. It took a year and a half to get pregnant with our first. Really anxious this time 😐
