I just want to be a mom

So my hopes are really going down the drain... so I've been having mild/dull cramps for a couple of days now. This will be my 3rd day, I'm now 11dpo with AF showing up on Saturday. Yesterday I told my fiancé that I think I'll be getting my period, I feel like I'm constantly going to the bathroom to check if she's arrived because I feel wet down there, and when I check it's just my creamy cm. I know I shouldn't count myself out until she shows up or I'm late, but I really think I'm out this month. I am so damn upset, I just want to be a mom!! Maybe it's not my time yet because god knows that a big journey is ahead for my fiancé and I, being that we are moving to the east coast in 5 months. But that doesn't stop me from wanting to get pregnant, maybe I'm being selfish.. has anyone ever thought they were out and then you got a BFP? I'm grasping to hope. Any hope
