- If you vomit or have diarrhea within 4 hours of taking your pill, follow the instructions for “What Should I Do if I Miss any Pills.”
- Missing pills can also cause spotting or light bleeding, even when you take the missed pills later. On the days you take 2 pills to make up for missed pills, you could also feel a little sick to your stomach.
- Decide what time of day you want to take your pill. It is important to take it at the same time every day and in the order as directed on the blister pack.
