long cycles annoying

I'm getting really annoyed. On bc my cycle was 28-29 days.... now I'm pushing 39 days this cycle!!!!! I thought maybe I could be pregnant. I've had possibly pregnancy symptoms. I've never had days of dizziness with out a fever or anything. I almost puked in the grocery store since the smells kicked my ass. I have taken two test. First response and both negative... it's day one late... ugh!!!!!
