My fiance and I have not had full intercourse but we have done other things (genital to genital contact) making it slightly possible for me to be pregnant. But I have been on this pill for at least a year now and have never missed a period. I was supposed to start 3 days ago and had cramping and slight spotting but now nothing. Took 4 pregnancy tests that were all negative. I did miss one pill during the sexond week but doubled up the next day. Should I even be worried about pregancy? Why would i miss a period if I never have before?
