I have been taking levin for about 6years and I have never had reguary bleeding but anyway my question is I missed 4 pills on my 2 week as I have been doing over time work and have been working nights I'm asking can I be pregnant as I had sex with my reguary bf a couple of the night And after those 4day I re took my pill and contionued my pill however 2 day later I had vomiting for no reason in the morning. Could be pregant or should I wait and see if I miss my pill
