Let me first answer this as an acupuncturist.. Acupuncture does not do what the body does not want to do. It supports systems to provide the means for those systems to eventually regulate themselves. I induce many women's labour and it just is not possible to do this if labour is not going to happen. As a midwife, I saw countless women medically induced and many of them did not respond to the powerful drugs used, because their bodies were simply not ready or willing. They almost always had caesarian sections. You cannot prevent pregnancy using acupuncture. Nor can you induce abortion, which is what you are asking for. Acupuncture is part of a complex system of health and the idea that a point will 'do' something is wrong. Knowing which points to use, and when, and how, depends on individual patients, and is a significant clinical skill which takes years of study and practice to get right.
Now I shall answer this as a woman. I first read your question late at night. I shut my PC down and went to bed but, could not sleep thinking about it. I wondered, however, if I had been asleep years ago when emancipation grew into feminism, if I had imagined the social/political/attitudinal changes that gradually gave women certain human rights; rights women and men fought and sometimes died for. The same rights that allowed you the freedom to have enough education to be able to use the computer you wrote this question on.
I say to you what I said to my (now grown up) daughters. No-one has the right to tell you what to do with your body. No doctor, priest, parent, or teacher. No sibling, spouse, colleague, friend, guru, politician, celebrity. You have the inalienable right to self-determination and autonomy. Your boyfriend, even if he were your husband, has no right to determine what you do or don't do on any level, but especially not your reproductive behaviour. Sister, I respectfully advise you to wake up and smell the coffee, and consider the implications of your circumstances; to free yourself from self-imposed tyranny; and to do it soon. Like, as soon as you have got to the full stop at the end of this sentence.
