help!!

Okay everyone I have been testing since i was 9 dpo. I am now 13 dpo (1 day before af is due.) I am STILL getting a bfn.. The more I test, the more depressed I become. I am trying for baby #2, and it just seems like I'm out of the game for this one because I'm still testing negative. Shouldn't I be getting a positive result already with 1 day till af is due?? I have had the cramps on and off, the other day for a few hours I had the tender breasts, I feel like I pee all the time!! My last period was July 20th, my cycles are usually 25 days apart, I had sex on the 30th of July and was supposed to ovulate that day but I may have ovulated the 31st of July. Can I still get pregnant if I did ovulate the day after unprotected sex instead of the day we had unprotected sex?? Should I wait until my period is missed to even test (which is tommorow?) I'm just desperate for answers, I'm really hoping

I'm pregnant!!
