Have you ever been so sure without being sure

Have you ever been so sure that you were pregnant, other than taking a test? We timed our baby dances this month to land just before and during the ovulation days. I've had symptoms and just haven't been feeling myself, spotted around the time that implantation would be, my husband and I had very similar dreams with babies, and period was a couple days late. Went to the store and got a test to take the next morning....and woke up cramping and bleeding. Feels like a knife through the heart even though there wasn't really anything ever there. We're just so ready to get our bfp.. 😞
