No period. Can I start birth control?

YES you can start birth control on ANY day. But make sure you take a pregnancy test first! The issue with an any day start however, is you need to take your entire first pack before you engage in unprotected sex, this is because without having had your period, there's no way to tell where you are in your cycle. This is how I started mine. I was 28 and had never had a period in my life, so we couldn't wait around to do a regular Sunday start, we just had to start when it was prescribed to me. All went well. I've been on them for 6 months now.

I agree with the above poster. Only a Dr can tell you if it is ok to start without waiting for a period. There are reasons to start at period time and if you havent had one you definitely need to clear that with the doc!

Taking the "pill" can help regulate your period, if this is a common problem for you. Talk with your OB/GYN and get a check up just to make sure that nothing else is going on before starting the pill.

However, is there a chance that you are pregnant and that is why you haven't had a period for a few months??? Have you taken a home pregnancy test or a blood test recently to rule that out??? Talking these things over with a doctor I believe is a good idea. I say this because of the irregularity of your period.

If everything is okay... and you still haven't gotten your period, then I believe you can start on a day that is convenient for you. You then take them on time and on schedule. It isn't uncommon to have break-through bleeding in the beginning but just keep taking the pill on time and on schedule.

I hope this helps you with your decision...
