I always get faint lines of LH

Becca
Got a pain in my left side so thought I'd check for ovulation. Slightly painful cramps on the left pelvic area. Tested even though I think I've already last week, as I never got a positive test never have. Missed a few test days due to my boyfriend being in the army.
Any advice would be helpful, my other app says this could be a sign of pregnancy such a implantion pains especially on the left.
