Too early or out of the race?

Courtney • Mama to Harper Grace 💕

My last period was 6/26/19, I ovulated on 7/8/19 and got a positive pregnancy test 7/20/19, I went to the dr today and they couldn’t find anything on transvaginal ultrasound and I’m just lost. They took some blood but my HCG won’t be back for a day or so. I’ve now had 5 positive pregnancy tests all different times of day and brands. Too early or out for the month? AF is now 3 days late
