Eileen • Engaged 💍 to my soulmate 🥰

So i am 9dpo and af is due dec 2nd. I been dying to test but been so scared yesterday i had two lh strips in my work draw.. so i decided to use it and got two lines and shown below. Can it detect hcg or maybe i have an lh surge before af. I been having two days of cramping and lower back pain something i never get until they day off af shows.. HELP..
