Negative test, no sign of AF.

Katie • TTC for baby #1
Hi all! 
My husband and I have just started TTC, so this is all new to me! I need some advice! I am on CD43 (usually have a cycle of around 34) and my period almost always starts within the predicted window. I'm over a week late now, took a test and it was negative. Feel totally off, exhausted etc. and still not sign of AF
Did I test too early and there's still a possibility or is this just a wonky cycle?  
If I'm not pregnant I just wish my period would start so we can get back to trying! Frustrated :(
