Two chemical pregnancies

My husband and I have been ttc for about a year now and we've had 2 chemical pregnancies during this time. The first occurred over Christmas at exactly 5 weeks and the second has just started now. I have already started cramping, my pregnancy tests are barely positive, and I'm no longer experiencing the few symptoms I've had. I feel like I'm at my breaking point. It's mentally exhausting to test every month for ovulation and then for pregnancy only to find BFNs. The answers I've gotten from family was "just keep trying, it'll happen" or "at least it was an early miscarriage." I am so ready to have a second child, but I don't know how much more disappointment I can take.
