That little voice.

So, I have had a little voice in my head telling me that I'm never going to have kids since I was 13. I'm almost 30. Ijust keep feeling as though I'm never going to have kids and cant seem to shake it. I feel it in my gut if you know what I mean. Lol. I'm married and we've been trying for 5 years with one miscarriage. Has anyone also felt like they could never get pregnant and still had at least one child? I'm just looking for a little hope. My period is coming and I'm so. Sad and starting to believe this feeling is right.
