I thought this was my month

I thought this would be my month! I've been doing my BBT chart and ovulation tests consistently. I had some wicked stomach pain/cramps the last week and a half, horribly sore boobs, runny nose, crankiness, extremely emotional, horrible acne, and super tired. Then yesterday non of my smptoms were present. That made me worry, but I decided to just stay busy all day and not think about it. This mornings BBT dropped. I am devastated! I'm out now, correct?
