Struggling

I feel so defeated we’ve been trying since August and nothing. We just got married this last month and we both want to start our family. I feel like it’s my weight holding me back 🤦🏻‍♀️ I’ve been trying to eat healthier and cut out caffeine but it’s feeling impossible. I know we haven’t been trying to long but what can I do to help boost my chances. Is it to early to go get checked out?
