Why is this so hard!!

Hey! So I am having a kind of down day. I don't have any anxiety but just sort of down. It took me 3 years to have my daughter and now we are trying for number 2. And I had some random light brown discharge today. Tomorrow is my big ovulation day. So not sure what the discharge is about.  We have been doing every other day and blah blah blah. But, I just am not looking forward going back down this road again. I absolutely hate how it's not something you can guarantee. It's a damn lie that it only takes once. I feel like that only happens in the movies:( And so I am just need some words of encouragement, if anyone has a few.
