Fertile window

Okay I don’t wanna sound dumb but me an my partner have been trying for a baby for a while now no luck yet but fingers crossed we get a blessing 🤞🏼 but I’m trying to get the right timing, If my periods just about match up with eve every cycle then should my fertile window be accurate? We try about once a day everyday or at least 3 days out of the week it says I should be fertile, I’ve done spoke with doctors and we are perfectly fine to conceive...
