Will it ever happen?

So this past few weeks I have learnt of a few friends who weren't trying and are pregnant. We have been trying on and off but seriously trying for 6months now and no success. Today is 10 dpo and I tested with a walmart cheapie and its a BFN. TTC has made me emotional for the better part of 2019 and I vowed I won't let it consume me in 2020 but when my LO keeps asking if his baby sister is in my tummy...I cant help but wonder when it will happen for us. I was honestly hoping this cycle was it and at least a vfp by 10dpo or so.I just feel like breaking down and crying and giving up all together on TTC.

Done ranting - no one else knows we have been ttc so I have no one to talk to. May God's will be done.
