my girlfriend have some brown blood on her undies , she was fertile when we had sex and i wore a condom , but it broke , so i accidentally ejaculated inside her, i let her take nordette as an ecp 12 hours after the intercourse, then another 4 pills after it , but a week after taking it, shes having a brown discharge, she says its dry and she only saw it in her undies , is it because she is pregnant or just a side effect of nordette? please answer she also experience breast tenderness , is this a side effect of nordette? or signs of pregnancy :(
