Q: Is it normal to skip periods when on a progestin only pills?

I have been on ortho-micronor (progestin only) since April and have only gotten 2-3 small periods at unknown times since then. Is that normal?? I also missed 2 pills w/in the same week about 2-3 weeks ago and now am worried about being pregnant, how soon after sex can I take an at home pregnancy test for it to be as accurate as possible? Thanks. ~Amber

The home pregnancy test is not based on when you last had sex; it goes by your periods. Since you are not having regular periods, it's harder for you. The standard is if your normal period is more than a week late, you would be able to get reliable results when taking a home test.

If you don't want to be tested by a doctor, you could take the hpt now and possibly a few weeks from now, take another.


If you miss two pills in a row, this information tells you what to do. It indicates you should abstain, or use a backup method for seven days.


What you are experiencing with your periods seems typical with a Progestin only pill. The following information was taken from this site, you can read more there:


"The most common side effect of the minipill is unpredictable light vaginal bleeding or spotting. This is even more common if you miss a pill or take your pills late.

You may continue to have your period at regular intervals, but it's likely to be lighter and might last longer than usual. Your periods could also become irregular or stop altogether. A small percentage of women on the minipill have prolonged or heavy menstrual bleeding."
