periods/conceiving

my periods use to be so irregular, almost as if they would never come, since august 2020 my periods have been regular and on time every month, idk why it’s changed but im hoping it’ll increases chances of conceiving. i’ve been having sex every day to every other day after the day of my last period but haven’t had any luck, does anybody have any tips? my partner and i want a baby but we’re having absolutely no luck and we’re starting to worry. please, anything would help if you guys know anything !!
