Trigger or bfp?

Hayle • 5 yr old daughter. 1 👼🏼 1-23-19. Ttc baby #2.

First picture is wondfo this morning 10 days post trigger. Bottom picture is 5:25 tonight frer. Is this a start of a bfp? I’m just confused because I tested out my trigger last round with wondfo and it was gone in 7 days. This is my first test this round and figured it was out of my system since my wondfo this morning was bfn. Which one is more sensitive?
