I was suppose to have my period 5 days ago tomorrow will be 6 days ago. I have been sleeping well at night but during the day I sleep like I haven't at all.I crave all kinds of stuff one minute its McDonald's the next its pickles next its cookies next its Taco Bell. I pee like a lot more often.I have been constipated a bit and when i lay on my stomach there is slight pressure and it hurts a little.I get pissy really easy lately and im always hungry.Also I have cramps that hurt and I feel nauseas too. To be honest I am starting to think that I am pregnant..what do you think?
