Sigh :( :(

Af should have come today but so far is a no show. I have creamy white cm and am so dizzy and nautious!! I just did a clear blue test and it says not pregnant! My stomach burns a little like af is coming but it did that this mornings very early and it didn't come.. The other thing is my joints - wrists and ankles are aching. I sometimes get that wen I have af. I'm hot as well! Like really hot. My question is, has anyone had all these period like symptoms with nausia too in early pregnancy? Shouldn't the test pick it up today if I was pregnant? Xx :(
