<s>[INST] Hi doctor Please my menses stopped on 4th of May an die had unprotected sex on 4th around 6pm and I took postenor2 around 8pm, but I have been having lower abdominal pains, no nausea, just that abdominal pains,  please does it mean am pregnant or is it the effect of the drug? Thanks Mandy [/INST] Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.According to your description the possibility of pregnancy is less as :-If your periods stopped at around 5th or 6th day of the cycle the possibility of ovulation around that period is very less in case of regular 28 to 30 days menstrual cycles.-As you took emergency contraceptive pill within 2 hours of unprotected intercourse the possibility of pregnancy is very less as you can expect around 95% of protection.So, possibly abdominal pains you are having could be a side effect of the drug which will contain higher dose of progesterone but you have to rule out the possibility of vaginal infection.Analgesics can you help in treating simple abdominal pain if the pain persist better to consult your doctor once and get examined.Hope answered your query and I will be happy to answer any further follow up queries.Take care. </s>
