Question: Switching birth control-Can it cause missed periods?

 CarryLA222 - Wed Sep 09, 2009 5:40 pm

I'm on the birth control pill (Orthotrycyclenlo) .
Last month, the pharmacy gave me the generic version of this pill
instead, but told me that it would still be effective for me to take. I took it.

It's been a week since I was supposed to get my period and I never got it. Instead, a light brown fluid leaked out for about five days on the week when I took the sugar/placebo pills (the same week when I usually get my period) However, there was no blood.

Could this be from switching my pills?

User avatar Hello,
It is highly unlikely this would be the cause. However, because of the hormonal manipulation that occurs with birth control pills, period irregularities are a common side effect. If you are worried about pregnancy, take a home test.

Best wishes.
