hello sir... thanks for trusting the healthcare magic doctors for ur health related queries. I guess ur concern is about..chances of getting pregnant aftr unprotected sex..right. my answer is- YES, there is chances of getting pregnant after unprotected sex,if u r not taking any precautions like- 1. condom 2. i-pill within 72 hours of unprotected sex. 3. male partner ejaculating outside the vagina. 4. if unprotected sex Will happens in the safe period(which is first from 1st to 9th day of cycle). u havent taken all theses precautions which described above. so in ur case there is CHANCE OF GETTING PREGNANT. DON T WORRY..RELAX.every problem has a solution... with the above small discussion u can try out my suggestions- 1.from the time u have done unprotected sex,,calculate it,if still 72hours has not been completed u can go fr i pill... 2.do urinary pregnancy test,tis test kit is easily available in medical store at affordable prices,buy it,ask ur grl to do it herself,,, if it is negative then nothing to worry...tis is only temporary relief,,, 2. if it positive,then rush to nearby gynecologist. he/she can help u. 3.if negative also still i insist to visit a nearby gynecologist fr further help. 4.ask ur grl when she is getting her menses..in next month if she gets her menses on expected date or 3-4days after expected date then she is not pregnant,,, i hope tis info was informative enough ,useful n helpful fr ur query.. regards:dr.sudha rani panagar... (first of al tis unprotected sex keeps bugging in mind among couples...besides tis u havent taken any precautions,,,tat has doubled ur tension,,,i can understand ur psychology....but dont take tension...every guy goes through tis stage..)
