Infertility after a MC. Success stories?

My husband and got pregnant right away with our now 2 year old son. I got pregnant again when he was 10 months old and lost the baby at 7-8 weeks. We waited a cycle, and now over a year later we still have not been able to conceive. It has been so hard on us. We love children and the thought of maybe not having anymore destroys me! And him! We have no went to the doctor yet. But if it doesn't happen in a few months, we are. We're mostly trying to save up for the costs as much as we can. Ladies, I sincerely need some hope at this point. We're both young, I'm 23 and he's 25. I take pride in being a mother. It's the most important thing in my life I've ever done and will ever do. 💙💜
