WHAT ARE WE DOING WRONG 😭😭😭

Maybe it’s because I haven’t been tracking ovulation correctly just over an app only for a month now!?! but we have sex ALL THE TIME !!! Maybe it’s because his sperm needs to mature and we need to hold off on BD and wait til that special week (ovulation) or whenever I have my fertile window... my periods are regular but irregular they’re regular to me(they aren’t the normal 28-30 days I’m 34-43 days each month) maybe I need to buy opk ?!? BUT MANNNNN LEMME RANT PLEASEE !!!😭😭😭 I just found out my younger sister is pregnant again! The first one she lost real early and she didn’t cry or care about the situation or anything!!!!! She had months to get her shit together (finish school ex.) and NEVER DID A THING and now she’s pregnant again. She doesnt even have a job!!!!!! And I know forsure she isn’t happy bout this situation either. And it’s like why God ? Why do you give her another child when she CLEARLY didn’t care about the first 😭😭 why can’t it be our turn already the ones who’ve been trying for years (we just started trying TRYING) but I’m speaking for others as well some woman didn’t even wanna be pregnant in the first place and here we are with baby fever high as ever getting emotional EVERY SINGLE TIME I SEE A BABY BEING BORN OR THE GENDER REVEALS LIKE 🥺🥺🥺 I’m not asking for advice or opinions I just needed to explode somewhere and here it’ is ... I think ima go get me a drink I just can’t rn 😭😭😭
