Period due yesterday, BFN

Amber • 23-Married. Currently Pregnant after 11 months TTC. MC May 2015
So AF was due yesterday. Got a bfn last night around 8 and one with fmu this morning around 530am. Typically I feel AF coming. I have that gross feeling in my uterus and spotting for about 3-7 days before.... Now, nothing. My discharge is clear/white/yellow (no infections, may just be my urine as I'm going off what's on the toilet paper) but what drips in the toilet is a white/clear. I can't help but think she has to show soon as I've had many bfn this year. The one BFP ended in mc. As much as I want a baby, I'm content with not being pregnant this month, I've overall prepared myself for that outcome (as much as one TTC can)  but if it's going to be another missed month, AF just needs to stop being a bitch and show up. I'd rather KNOW I'm not pregnant than second guess everything. Any advice or opinions so I maybe stop stressing? I was thinking I should wait until Christmas to test but I don't wanna ruin my day with yetanother  bfn.
