Tired and confused

So we have been trying for 19 cycles with no luck! I’m currently 13 DPO and I had mild spotting at 4 DPO and the last 5 days have consisted of eating everything in sight, slight cramping, sharp pains in my breasts and my lower back hurts, I’m also peeing every 2 hours. I took a test at 10 and 11 DPO and i had one faint line and the gals on here said it was an indent line the other was negative. Should I keep testing? AF is due in 2 days! I’m just so confused
