Last night I was researching possible reasons AF has yet to show. About midnight I got terrified that my dark urin was liver failure and not dehydration. So, I got out of bed, forced myself to drink 5 10 oz glasses of water and went back to bed. An hour laypter, as I was getting really into sleep, I started waking up every 45 mins to pee. I think it is safe to say I am hydrated now.
Now for the late ad/possible pg situation. Going to wait and test Mon. It is possible to be pg with hcg levels still too low to register on most hpts. If no af and still neg on Monday, will call my ob and try to get a blood test.
