AF is five days late!!

I took this test this morning with FMU. I'm pretty sure it's a BFN, but maybe someone could tweak it. I've been experiencing cramping on and off the last few days with lower back pain. I feel like AF is showing, but nothing. I noticed this morning a tiny spot of pink spotting, but nothing else since then. I usually don't spot before AF starts. Can implantation happen after a missed period? I just wish my body would tell me what's going on!! My husband and I are leaving to go out of town this weekend and I either want AF to come before then or have a BFP to surprise my hubby with! I'm praying for a BFP!! 🙏💖👶👪
