Somehow I either took 2 pills in one night or I lost a week 3 pill. I am a Sunday starter and I didn't have a pill to take Sat. All I saw in the booklet was if you miss 2 in a row, but I didn't see anything about 1. Should I just not worry about it or should I be careful? I had a terrible headache and didn't feel well on Tues. I thought it was allergies until I realized I was missing a pill so maybe I took two Monday night???
