If you ovulated sat and didnt have sex till monday,then you probably missed it.however if the line went blue sunday your egg will survive up to 24 hours so you may have got there,ideally though you need have sex at least 3 days leading up to ov,as sperm can survive up to 5 days in fertile cm,im also using ovulex how are you finding them,
i started ovulating saturday night and i had sex early monday morning do u think that i missed it i used the ovulation kit and the lines turned blue sunday morning im also using ovlex so i hope i made it this is the thrid month of trying
Sperm can live in the vagina for up to three days. So yes, that is enough. Most women who really know and understand their bodies, have sex one day before ovulation, and one day after. But you'd be fine just having sex once. Just be sure you ARE ovulating. :)
