No, I think you're probably very safe. You did just what you should have done.

Just to be on the safe side be careful the first week of switching. In a very very few switching the hormones in different bc can up your chances of getting pregnant. Just treat it like you just started bc. But remember I said this happens to a very very small amount of women. For the most part you SHOULD be just fine!!

Um no. That is not medically sound advice..

ALL birth control pills contain basically the same hormones, just packaged under different names.

TRINESSA is the same pill as Ortho lo, just a higher dose.

What if she were doing it the other way around and switching from trinessa to ortho lo? Would going from a higher amount of hormones to a less amount make it less effective because her body isn't yet adjusted to the lower amount and is used to much more?

Like I said before the majority of women don't have this problem. The doctor thinks that is what happened to me, I went from the depo to a low dose pill and ended up getting pregnant. Because of the time frame they beleive that is what happened. So yes it can happen. And I'm not a Dr so medically sound advice should come from them. I'm only talking from experience. She is worried about it. So you can give her advice. Just like you do to many many people. I was advised any time I switch a bc to be careful and treat as if I'm starting for the first time. So it's just my advice please don't tell me I'm wrong, I don't tell you when I may think your wrong because you might have something behind what you say, that you beleive what you say is correct. Everyone has different experiences and knowledge. That is what you give to someone

Oh and I do work in a pharmacy every day! So yes I know most bc contain the same hormones and the bc can have different names. BUT many bc's do have different hormones or different combinations it can effect different women in different ways.

But it's the dosage and the secondary filler ingredients that women react to, and that's why a woman who switches from one pill to the other does just fine.

Right...

NO, the dose does not matter.

AS long as you begin taking the pill directly when your placebo week is over, then you are protected.
