trying to conceive

today was the last day of my period, i ovulate on the 15th but i’m not sure how accurate it is. my periods use to be really irregular, almost as if i never had one but since august 2020 my period has been regular and on time. my partner and i have been trying to conceive for a year now, we’re starting to lose faith :( does anybody have any tips? people say not to worry/ try so hard about it so much but how can you not? i really just don’t know what to do anymore, its starting to cause the both of us to worry because of how long we’ve been trying. we want our rainbow baby 😔❤️
