Feeling consumed with TTC after MC

Annafantanna
Hi ladies
It's my third cycle after MC twins and got a huge BFN this morning, feels like AF is going to show any minute. Anyway I am finding myself feeling incredibly low every time AF shows. Feel like trying (and failing) to get pregnant again is consuming me and it is all I can think about. Doing everything we can and it's just not working, just feel so helpless. Any advice on how to shift the focus so that I'm not confatanly feeling fraught?
Would love to hear your stories x
