Hello, I am 5 days late on a 40-42 day cycle pattern, I only had sex (unprotected) once since my last period it was on Oct 26th. I have lots of bloating, gas, have been dizzy and light headed for weeks, sensitive to smell, emotional, everything tastes funny, very frequent urination and so on, I have taken a test and it is negative. I am concern because if I am not, what else might be going on? Should I be concerned, or could I still be pregnant? The time frame doesnt seem to work out to me.
