Grumpy and lots of signs of being pregnant but negative tests ???

I know this might sound a bit weird but when I am pregnant my eyes change colour from brown to green I know this because I've had 5 misscarriges and my mood swings are crazy ...... the last few days I've been flying off on one been really moody to my partener and our little girl ( my step daughter ) and being the same to his friends when normally I'm perfectly fine but my eyes are green and my moods are really bad done 2 tests yesterday and negative and one this morning as morning testing is best but all 3 came up negative not due period for another 11 days so god only knows what's going on ..... plus I'm going on holiday to Barcelona in 4 days so thought I'd test to see just in case before I go but nope negative ..... 🙄
