I'm concerned 😓

I've been try really hard to get pregnant for 9 months. I know doesn't sound like a long time but feels like an eternity 😩 I have normal periods, which are heavy. They come from anywhere between 28-30 days, one time it's was 31 days. I get a period every month. I'm afraid maybe is something wrong or the app is calculating my ovulation. But I log everyday. I guess I'm just really frustrated. I also freak myself out because of how my periods are, even tho I get them every months. I suppose I'm just venting to anyone who will listen, and maybe give some advice. Thanks guys ❤️
