Combination Pills ineffective for 7 days--Plan B?

[etudexc]

Hi,

I just started taking combination pills (Lutera) today, and I was told that this would not be effective for 7 days so I should rely on other forms of birth control such as condoms. However, my doctor also gave me Plan B. I was wondering if it would be detrimental to my body in any way to take Plan B if the condom breaks/improper use occurs? Is Plan B safe and effective during the first 7 days when my pill is technically ineffective? Some forums online say that Plan B is unnecessary and could severely mess up your hormones if you're taking it while on BC, but because I'm still in the 7 day ineffective period, does the same consequences apply?

Thanks

There's no harm in taking Plan B while also taking the pill. It's not going to "severely mess up your hormones" if you take it; it can throw your cycle out of whack for a bit, and it isn't necessary if you've been using the pill for a while (just because the pill taken properly is more effective) but it's perfectly fine to use with any hormonal birth control. If your doctor didn't think it was safe for you to use, they wouldn't have given it to you.
