Defeated.. am I out??

I thought for sure I was pregnant this month. I had cramping off and on my whole TTW and my breasts have hurt more than ever the last 2 days. I have been super emotional, mood swings and all. I kept trying to tell myself the test would be negative but despite prepping myself, when it came back as negative this morning I was crushed. My period is due in 2 days and I think my estimated ovulation was right because I had ovualtion cramping and cervical mucus that coincided with the days. Im probably around 12 dpo.

Anyone have a negative at 12 dpo and go on to have their BFP?!?
