Late BFP?

Layla

Hi I’m trying to conceive, I usually have 31 day cycles and ovulate two weeks before my period. I baby danced two days before, the day of, and two days after my predicted ovulation date. I am currently 3 days late, day 34 in my cycle, 18 DPO, and took a test with it being 100% negative. I am usually very regular. I am extremely crampy and my breast’s have been sore on and off. Is there a chance I could be pregnant?
