Help me I need hope

I am 11dpo today and AF is due Sunday. I got a BFN with fmu this morning. I am starting to feel like I am out. I don't have sore breasts or anything and I usually do when I am pregnant. I have my normal pre-period acne breakout which is actually a little worse than normal. Has anyone had a BFN this close to AF one day, and then got a BFP the next day or two? I hate feeling this way! Please share your experiences!
