Need some patience

Katherine
So I am lucky enough to have three wonderful children with my husband and I understand that if I get the privilege of one more I'll be over the moon 
The thing is all of my others were surprises!  So the actual trying bit has never happened. Until now!!! How do you guys do this and stay calm 
I'm an emotional mess, I stopped my pill 2 months ago (mini pill) and really feel like I'm being dragged through a hedge with pms at the moment 
I just can't find the patience to look at what I need to do next.  I know it's early days but any other advice would be appreciated xxx
