am I making something out of nothing?

me and my partner have been ttc for a little while now and last weekend we tried when I was supposedly at my most fertile and the past 5 days I've not been able to shake this nausea! I never normally suffer from nausea unless I'm ill but it's been so bad that I had to take a day off work because I've been throwing up! as well as this I've been getting some cramps but i never usually get cramping at this point in my cycle, i also noticed some light spotting yesterday, is it possible these could be super early pregnancy symptoms or am i just being hopeful? I don't want to take a test as I feel it's way too early...any advice would be greatly appreciated!!
