I do believe that any bcp's should be stopped immediately upon discovery of pregnancy (if she is planning to keep the baby) to minimze the risk for damage.

I got pregnant on ortho tri cyclen lo 7 weeks ago.....Didn't know it....Didn't stop taking my perscription.....Last thursday I had a miscarriage....Hope this helps. Check out the ortho lo website...There is some good info on there. You should also get a blood test done to figure out if you are pregnant. But keep in mind because of being on the pill it is not likely to show up right away.

Thanks ladies so much for that information.
