Its my first time taking birth control. I have not started a pack yet because I been waiting for my period to come again. I know usually women should take the pill the Sunday after they get their period. Or if they start on a Sunday, take it on a Sunday.. right? Well what if they start on a Monday.. can they take 2 pills that day for the first time. Or should they wait until another week to start it?

For instance...
I got birth control a couple weeks ago.
I been expecting my period around this week.
Yesterday was Sunday July 19th.. today is Monday July 20th and I have my period now.
So would I start birth control Sunday July 26th for the first time?
Or can I begin my first pack today and take 2 pills today? One for Sunday and one for Monday?

You start taking the non active pills now.
That is how I have always done it.

Start with the non active Monday pill now and continue through until you finish the pack.
Time of day does not matter, morning, night or midday, whenever you are most likely to remember to take it.

Taking 2 pills at once is only in an emergency when you have forgotten to take a pill one day. Don't forget!

ii know usually women should take the pill the sunday after they get their period. or if they start on a sunday, take it on a sunday..right?

That's what my doctor told me, so yes, if you want to start taking it next Sunday that should be fine.

And Shaz is right, while you're on your period you should be taking the non-active pills, but since you haven't started your pill pack yet you don't need to take them yet.

Good point Marie.
I usually start taking the non active ones to start with just to get used to remembering to take a pill every day though ;)

It is probably not how you are supposed to do it though, I have just always found it easier :o
