I had sex with my bf on January 17th, a day after my fertile window ended - according to the app clue (which i know its not 100% accurate)- for the first time & He ejaculated in me with the condom on but im still alittle paranoid of the chances of me getting pregnant even though we used protection. If it helps My last period was from december 29th - Jan 3rd & my next period is not until The end of this month but im still worried i might miss it because of be oming pregnant.
