Positive test than negative same day

Raina • Wife • Baby #2 due 7/16/19 • Lost our daughter, June Carter Z, to SIDS 6/7/18 • 21 years old • Chronically ill with POTS

Am I pregnant? The first test I took 2 hours ago than the 2nd and 3rd I just took. First is clearly positive, second is a very faint line, and the 3rd (digital) is a clear negative.

Period is supposed to come in 1-2 days.
