yes for now you need to take i-pill to avoid getting pregnant within 72 hours preferably within 12 hours. but emergency contraception is not to be taken on a regular basis as it has progesterone and as you have been diagnosed with pcos (polycystic ovarian syndrome) there is already a long follicular phase (first phase of the cycle). you should consult a gynecologist for regular contraception like low dose oral contraceptive pills as they even help in pcos and regularising the cycle. for further information consult an obstetrician and gynaecologist online --> <link>
i have pcos and had unprotected sex. are there chances of me being pregnant?
