giving up? or scared?

Elizabeth
I had a miscarriage in Oct after having healthy kids.. in 2012 and 2015. We were really excited to have a third. But things happen.. here I am now.. really wanting a third and we've been trying. I had my first normal period last month and this month I'm. Late by 6 days! I've taken many tests and all negative.. I feel so discouraged 😔 I wish something would happen even if it's just my period.. ugh anyone else feel this way? 
I seriously want to give up at times.. I mean I have two kids but I always saw myself with 3.. the next two months are really the breaking points of if we continue this.. it's too emotional.
