I'm on the blue pill , the one close to the dark green pills . I took this pill before and stopped because my period was two weeks long . Now that im taking it again , theres no period at all , just brown stuff . And I had sex 4 days ago unprotected but I'm sure he did not ejaculate inside me because that's not what we do , after a little sex we use oral to make him ejaculate . However I'm still afraid that I could be pregnant but is it the birth control pill ?
