Oh and to add, I was taking it for the first 9 weeks of my pregnancy because I literally had no clue I was pregnant.
I was taking lo loestrin 24 fe, never missed a pill and I got pregnant on it too. My doctor says he is not worried, but I was (of course). Im not a dec mom, im just lurking here :) Im 14 weeks and so far baby is doing just fine
I don't think it would have any effect on the baby at this stage. Just make sure you stop taking it now. If you are really concerned check with your doctor but I don't think you have anything to worry about being that you are early in your pregnancy.
