I was late in taking pills twice this week, so I took two. Then, for the next two days, I took two pills each day. I have waivered between constipation and diarrhea since then. I am relatively certain that I ovulated this past Tuesday. I last had sexual intercourse on Sunday evening (7/6/2008), so I don't think I'm pregnant. But you never know. Has anyone else had to take two pills due to missing pills? I'm sure I overmedicated, so that could be a reason I've teetered with being sick.
