Unless you chart your BBT or use OPK's it's impossible to say when your fertile window is. You can guess using ovulation trackers, but it is still only a guess and at the end of the day a guess is pretty useless--especially if you guessed wrong.
Many things can cause a late/skipped cycle, so try not to put too much thought into it. Stress, sex for the first time, medications, poor diet, poor sleep habits, etc.
And I'm thinking that I'm not because it wasnt during my fertile window either
Still no period, I know worrying delays it but i don't even feel close to my period.
First Response is the best test on the market. If you took it properly and within the proper time frame, it should be accurate.
No matter how many you take? :/ is "first response" realible?

You can also ask your doctor for a blood test. Not to worry you but I know many women have got neg preg test but a positive blood test.
It's always possible that you could be. Wait another week to see if you get your period and if you don't, take another pregnancy test with first morning urine. Since you both worry, you should also look into getting on birth control in addition to using condoms as added protection.
