First sign you were pregnant?

Help!! What was your first sign you were pregnant?

I've been suffering for days with bloat, tender lower stomach and my boobs are killing me!!! I'm in agony if i try to sleep on my stomach and I've had insomnia bad recently. I had a negative test today but I think AF is due next week (glow kept changing my dates so I've no idea really)...
