How do you keep going

First it’s worrying about getting pregnant and baby dancing the right time. Then it’s the worry of checking ur underwear every minute for bleeding or spotting and second guessing every cramp or twinge in your body. Then it’s the worry of HCG levels. Then it’s waiting week after week for the u/s screen to show growth and Ive ever got passed 8 weeks ONCE. The I’m sorry and tears consume me for weeks before I start spending endless amount of money on OPKs and HPTs. I’m tired. I’m hurt. I’m broken. I can’t continue like this.
