<s>[INST] My boyfriend was at my house 11 days ago and pretty much we did oral and there was a little bit of precum and about 5 minutes later I rubbed my clit area on the underside of his penis for a few seconds. I am on the birth control pill but I m still scared that maybe I could be pregnant. I started my period today (I usually start on Wednesdays) and it s brown like usual but I can t help but still be scared. My boyfriend thinks I m overreacting and sometimes I think so too. Could I be pregnant? [/INST] Hello misunderstand your concerns you are already on the birth control pill, pregnancy is not possible (if you are taking it regularly without missed any pill). Birth control pill is very effective in preventing pregnancy and failure rate is just 0.5-1%. Pregnancy is not possible as period is already came. So do not worry. You are not pregnant. You can clear your doubt by doing urine pregnancy test. It will definitely come negative. Hope this may help noncontact Chat Doctor for further health issue. Best regards </s>
