Afraid I'll never be a mother

Amber • 26 / 28 years old. 8 years together. 6 years married. Currently trying to conceive!!
I suppose it's kind of silly to freak out over, especially since my husband and I have just started ttc. I'm 26 years old, and have always wanted children. I have always see myself as a mother, but for the past few years I feel like I will never be one. More lately because of how irregular I am. I feel stupid for making myself freak out and have these insecurities especially when I am so young and we haven't been ttc. My husband and I have been having unprotected sex for years, and even though i never tracked my fertility until now, I just feel like motherhood will never be something I will get to experience with being pregnant and such. I suppose this so irrelevant and I probably shouldn't post this, because I should be positive and excited for trying for a baby finally, and it won't stop me, I was just wondering if anyone has ever felt this way before, or are currently are.
