I feel defeated

Welp i started my period through the night. I was hoping to wake up this morning and take another test, but once again Mother Nature strikes again. I’m very overwhelmed and just feel hopeless. My periods had been regular the last two cycles but this cycle my period came a week late. I don’t know what else to do. Getting pregnant again almost seems impossible. I’m just so heartbroken yet again. I want my rainbow baby so bad. And now I’m back in this funk because i feel like something is wrong with my body.
