Update! CD 41...no bfp..no af...

Ok I am now at CD 41. Having a lot more symptoms but no AF and no BFP. I don't know what to do, I'm so confused. All my friends think I'm pregnant, and I don't want to get my hopes up. I really hope that I am. I've been nauseous, and have been super hungry, and been taking naps during the day ( which I never do ). In the past 24 hours, I've also developed dizziness and lightheadedness when I stand up and have also been getting really bad cramps in my lower abdomen. My lower abdomen when I stand is super hard and I seem to be peeing a lot more. My period was supposed to be here around October 2. I am never late. My cycle days run around 32 days. Should I still have hope? Some encouraging words would be really helpful....
