I am now on day 9 of not getting my period. I prolonged my birth control 4 days so I wouldn't get it when my husband came home from work. And normally it comes right away but it's been 9 days and 2 negative tests. On the 4th day of me ring late I had light brown discharge only when I wiped but now nothing. I don't have any symptoms or sore breast. Could I still be pregnant?!
