My Girlfriend Usually have some bleeding effects 1st or 2nd day after taking her birth control Pills. The thing is that we are scared that they might have not been effect this last time because the regular bleeding starts One day or two days after taking the pills and is not present and this is the 4th day. We usually have Unprotected sex and after the sex she takes the birth control pills few hours later. That is how we do it for 5 months now but this time no bleeding period after taking the pills. We are scared that we might be pregnant or rather, she my be Pregnant. What can we do ?
