[/INST] Hi, You had unprotected sex during safe period and emergency contraception (chances of pregnancy is least) were taken and later developed pain abdomen. Some time patient may develop abdominal cramps due to side effect of Progestin only pills but it subsides within 3-5 days.  So give her ANTI-SPASMODIC, MESENTERIC ACID (NSAID), PPI and if symptom persists then visit gone clinic for clinical evaluation n investigation including USG abdomen and treated accordingly. </s>
