She is having pain in stomach and geneticals. please suggest me as soon as possible. [/INST] Hello, well from the history you have given, both the pills are effective in preventing unwanted pregnancy when taken within 72 hours of unprotected sexual intercourse.....i would also suggest her to take lots of fluids and void, and keep her perineum clean to prevent infections...she cam take some antispasmodics for pain abdomen.....hope i was helpful to you. .. </s>
