Positive then negative

Courtney • Wifey 💍 TTC #1 👶 Momma to an 👼🏻

Okay guys please help. So this morning I took a test after trying for 5 months I finally got a positive. About 6 hours later I took another test and it was negative. Both were early detection. Could I be very early and my levels were not high enough in the evening that’s why I got a negative?
