I was feeling queasy and thirsty yesterday too. I thought it was from the bottle of wine, 4 jager bombs, and 1/2 a beer I drank Saturday, but maybe I am preggers !!!11!1!!
Seriously OP take a test once a week until you get your period, a + test, or hit 60 days with no period. If you hit 60 days, call your doc and he/she can perscribe meds to jump start your period.
I recommend charting your BBT. It takes the guesswork out of knowing when to test.
