This is difficult

I went to my Dr last month to make sure I can have kids due to the fact my iud was in longer than it should've been. He said I'm fine since I have been having regular periods since i got the iud removed. He prescribed me prenatals explaining it will help with my folic acid levels ect which will help with having a baby if I get pregnant within a year. I know it takes time to get everything going the right way, but it get depressing sometimes. I'm 23 I shouldn't be having these issues, everyone I know is expecting or has had a bundle of joy. I'm happy for everyone of them don't get me wrong. But it makes me sad that I'm trying and so far nothing, I wish to be able to have the experience of motherhood, carrying a life in me. *sigh you can only hope right? Sorry for the rant. I'm just a little down.
