IUI #2 failed

Period is due today or tomorrow, and pregnancy test is negative. Big bummer. My husband and I have talked about skipping next cycle, just to relax and get rid of stress. I really don't like having to go through all this. Plus, my birthday is in 2 weeks (probably when I'll ovulate) and while it'd be great to do it then and potentially conceive on my birthday, it's too much pressure for that. I'm turning 30 and a little sad. Since we got married (when I was 22), I wanted to be done having kids by the time I was 30. I wanted 3-4 kids. We have 2 (born in 2018 and 2020) naturally, though it took a while to conceive. But my husband was also diagnosed with cancer in 2018 and since then, it's been a roller coaster. He was in remission until 2021 and finally he's in a more stable place now and we can try for another baby. Though because treatment sterilized him, we have to go this route. And it's just a pain. I'm so frustrated. I wish things could go the way I planned. I'd have my 4 kids by now, my husband would have a clean bill of health. But maybe we were never meant to have that. We'll give it 2 more tries and be done. We don't want to pursue IVF if IUI doesn't work. I know everyone's in a different place in their fertility journey, and I hope every one of you gets the answer to your prayers and hopes.
