Quit playing with my damn emotions—positive then negative?

Brit

So last night I took the first UPT (first two pics) and it appears to be positive. Now this morning, it’s negative (the last pic). Am I losing my mind? Would you go have a blood level drawn? I’m asking because my progesterone is borderline low and I need to know if I’m pregnant ASAP to possibly start supplementation but now I’m just emotionally exhausted and don’t know what to do.
