Confused

Katt

So my normal cycle has been varies for the last 4 months. Irregular 26-31-28-til now which is 43 days. Longest time ever not to have period. Done ovulation tests all the way through and no ovulation until 17th of this month. Which had smiley and bright positives. We did inseminations on the 17th to. I’m still waiting for period. And if it was real and positive for the ovulation. When do I even start a pregnancy test. I’m literally confused. Any help from some one who has irregular periods plz
