I missed the 2nd pill of my pack this month then caught up! Then sometime in the second week i ended up missing 2 pills and had no idea! I figured that out on a night i was actually throwing up, i still ended up taking one pill after i thought i was done throwing up and on an empty stomach but i woke up about 4 hours later and threw up some more. The next day is when i finally started to take 2 pills a day to catch up. Could i have thrown my body off so much that i could have ovulated?
