I have never had sex before, but my boyfriend and I have engaged in oral and we've done stuff with our hands. I recently was supposed to get my period, but it hasn't came. I have all the symptoms but no bleeding. I have been on birth control about seven months and I have usually gotten my period by now. When giving him sexual actions, he did not give off sperm, but could I be pregnant? If not, could you please tell me what is happening.
