Hi , Thanks for writing in. According to the information you have provided if September first is considered as the first day of your period then you are approximately 9weeks pregnant now. This date calculation works best if you have regular periods and have a cycle of 28 days. As you say that your pregnancy test is positive and you still havent got your periods then there is no doubt that you are pregnant. At this point of time I would suggest that you visit a Gynaecologist & Obstetrician and go for a Medical Termination of Pregnancy. Take some near or dear one may it be your parents or boyfriend in confidence to help you. I would not suggest taking any medicines for the same as its not safe and can lead to complications. You should hurry up now because its already been 9weeks and as the pregnancy advances termination becomes more difficult and the length of the pregnancy must not exceed 20weeks to qualify for an abortion. You should go to a qualified doctor and the clinic which is certified for the same. Hope this helps.
