Emotional exhaustion due to chemicals

I obviously will be speaking to my doctor as soon as possible, but I know they aren't gonna know what's happening either.

I have a healthy baby boy born dec 2020, which I'm so grateful for. I had one known chemical before him. Confirmed by blood tests. Numbers sank and it wasn't viable.

I've been ttc again. I've had a chemical in both June and July. No question they were positive right before or day of expected period. One of them confirmed with digital. Then AF comes. The lines fade. My hopes crumble. I'm trying to be positive every time I get two lines but it is taking a toll on me. The excitement, hopefulness, then it's all gone in a second.

Well, I'm getting two lines again this month. AF due today. I noticed some slightly tinged cm that barely shows up when you wipe. So Im starting to get concerned that its happening again.

I don't understand why I keep having chemicals. I'm shocked to have fertilized an egg each month over the last three months. Just to have it be fruitless.

I've been working out, eating well, taking my vitamins... I just wish I knew why they keep failing

I don't really know why I'm posting this. I just feel alone and want to talk to others about it.
