Needing advice and someone to talk to

Lexie • 1 month ttc baby #3

So recently I been emotional and sad trying to stay strong and not think about it but it’s so hard me and my partner haven’t been having any intimacy due to our daughter waking up every time we are about to do it and him being so tired after work. I wish it was easy to get pregnant all I want is to grow my family and have my daughter have a sibling. I feel like I’m failing. I don’t know what to do. I need advice. People tell me when you don’t think about it , it will happen.. itshard not to at this moment due to us Barely having intimacy and to add to that I haven’t had a period last month with a negative pregnancy test.
