AF finally showed and I just want to cry 😭😭😭

I really thought this month was different. Especially been 7 days late. AF just showed. But I guess I thought wrong. I just don't understand how I got pregnant so quickly the first time, but it ended in a miscarriage. Now that I'm actually TTC, I can't get my rainbow baby. I just don't understand! Is there something wrong with me? I'm so tired of seeing everyone else fall pregnant. When will it be my turn again? When will it be my chance to know what's it's like to have a child of my own? I know I'll be a good mom. All I want is a chance 😢💔😔 Is that too much to ask for??
