Thanks for your question. I’m not sure what you mean by “I am having break through bleeding?” Nonetheless, it doesn't seem that you are pregnant... but you can do a home pregnancy test to confirm or exclude possible pregnancy. Your epilepsy medicine, Keppra (levetiracetam), belongs to drugs which are in pregnancy category C ... which means it can cause fetal damage. Oral contraceptives are not recommended for use during pregnancy and should be discontinued if you become pregnant or think you are pregnant. If oral contraceptives are accidentally taken early in pregnancy, however, problems in the fetus should not normally occur.
