Given up ttc!!!

Given up ttc after nearly 3 years it would be my second too I've been to the doctors there's nothing physically wrong with me nor my partner I don't know what else I can do maybe I'm just not ment to have a big family like I've always wanted why is it you can't have the things you most want! Is it too much to ask to have a loving partner 2-3 children a family home & complete it with a puppy & go for long walks in our wellies on muddy days etc with the kids and dog! All I want is to be able to see my daughters face when I tell her she's going to be a big sister like she keeps asking for and lay in bed at night with a big bump keeping me awake with a big smile on my face because the reason I can't sleep is because I have a little person inside of me working hard at growing into my our beautiful little baby  sorry for dragging on and ranting does anyone else feel like this do I give up or do I keep trying 😢
