Is it advisable for me to consider taking Plan B if my partner did not complete ejaculation during our intimate encounter? I find myself pondering the potential implications and risks associated with this circumstance. Could it be possible that pre-ejaculate fluid might still contain sperm, thereby posing a risk of unintended conception? How effective is Plan B in such a scenario, and what factors should influence my decision? Would it be prudent to consult with a healthcare professional before making this choice? Furthermore, how do I assess my menstrual cycle’s timing and its relevance to the efficacy of emergency contraception? Are there any particular precautionary measures I should take to ensure that I remain informed about my reproductive health? In light of the complexity surrounding this issue, what are the prevailing opinions and evidence from medical experts regarding the use of Plan B when ejaculation did not fully occur? What steps should I take next?
