Hi, my name is Sara and I switched to Portia two or three months ago. I used to be on Levora, but they switched me to the "generic" brand. I have had trouble trying to find which time is best for me to take it so I keep switching it from month to month, but only between packs. Three days ago I started getting a light brown discharge when I would go to the bathroom and I'm not supposed to start my period for another week and a half. What is this stuff? What does it mean? Also, I haven't ever forgotten to take a pill although I may have taken them at different times (within one hour) of each other. Should I get a HPT?
