Ovulation test question

Annalisa

Hi, I am 31 and recently started TTC. Hubby didnt want kids and then changed his mind as I wanted to try years ago! Anyway I got some ovulation test sticks. Today I took one and got a positive so think that means I will ovulate in the next 12-48 hours? My question is my hubby has been away and isn’t back until tomorrow. Will it then be too late? If so I will be so gutted :-( but I could ovulate tomorrow and still be ok? Just unsure how it all works and so desperate!

Thanks for any advice! X
