My boyfreind and I are planning on having sex in a week. I have been on birth control for a year but I haven't always taken it at the same time everyday. I just started a new pill pack after skipping my period from the last . I would like to know if my chances of getting pregnant are high? If they are I don't want to have sex. Getting pregnant would ruin everything for me. I am also a virgin so I know nothing on this matter. If he comes inside of me, will I need to get an emergency contraceptive? I.e plan b?
