Daytime test

I know I’m prolly pushing it here but I’m trying to surprise my husband with a BFP. We weren’t going to try for baby #2 until after summer but I’m fairly certain I am pregnant. I am cramping with sore boobs. I had implantation bleeding yesterday. I rarely even cramp during AF and I never have sore boobs except when I was pregnant with my first. I’m currently 8dpo and AF is due in 6 days. I have bought the first response that claims to be accurate 6 days before missed period. I tested yesterday and BFN. I’m going to visit some really close friends this weekend and would love to have a big reveal to my husband then but not sure I’ll get a BFP in time. I want to test today since it’s 6 days before but with a negative yesterday idk if it’s worth it. I also would have to test mid day since I’ve already peed once today. What do you ladies think? I’m leaving tomorrow to visit friends. We will only be there for 2 days.
