<s>[INST] hello,me and my husband were intimated on the 15th day of my mensural cycle.we are always  careful during our intercourse. but this day he is confused whether a little of the sperm had entered inside. will i be pregnant. is there any remedies to prevent. [/INST] Hi, If you have a regular 28-30 day cycle, perhaps you had intercourse around ovulation and there is every chance of conception if conditions are favorable. If any protection was being used, chances are lesser. If you wish to prevent any pregnancy, you should get emergency contraception as soon as possible after the act as any further delay would make the medication useless. If it happened more than five days ago, then, the only way out is to wait for your next period and get tested for pregnancy if you miss it and go for a medical abortion under medical supervision. Hope this helps. </s>
