Got a static smiley face on clear blue advanced ovulation test last night 
Me and DH have been DTD for a few days including yesterday as my app said yesterday I would ovulate and although the result was late I did!
However, I used cheap ovulation tests off amazon around 11:30am and they’re negative
I thought you’re supposed to ovulate for 24 hours after positive result. I had used the clear blue around 5pm and got flashing smiley so between 5 and 9pm I must’ve ovulated.
Will I have only briefly ovulated or is this normal? Is it just different tests having different results? Going to try again later and not drink any fluids (had 2L already today)
Sorry if I come across quite dim, this is only our second month w/o contraceptive and our first official month TTC so this has all confused me beyond belief!
