I've been on birth control for almost 9 years. My partner and I had sex and I wasn't sure if he pulled out soon enough. I know that there is pre ejaculation prior, and we never had a problem before but I just get worried. Should I take the Plan B pill just incase? I know it's going to mess up my cycle and I just don't want to go through all that. I am good about taking my pills, I take them at 9PM every night.. if not at 9 it's at least an hour before or after. What do you think?
