Ginette 35: Your low dose bcp is effective unless you miss taking an active pill after the placebo week. Your symptoms might mean pregnancy, so get a serum HCG test to make sure you are not. In general, take the low dose pills the same time each evening, and start a new pack on day five of the placebo pills (not day eight). This will insure you do not ovulate.
