3rd baby on the way!

I need advice from someone whose gone through a similar situation or just someone to listen. I just found out that I'm pregnant with my third child, while I am well aware that many struggle to conceive and I was blessed to get pregnant on the first try I can't help but feel sad. As soon as I found out I was crying non stop, I do have an amazing husband but I just can't help but feel the way I'm feeling especially with having a 2 month old I feel like I won't get to enjoy him as much as I enjoyed my 7 year old. I apologize if my post offends anyone, and thank you ladies for letting me vent.
