<s>[INST] I am a married woman........ 15 days ago, my husband enters his penis into my vagina just for 2min without any protection........ is there any possibility to be pregnant....... actually i am studying master degree........ so i dont want a baby right now........ pls help me......... [/INST] Hello and Welcome to ‘Ask A Doctor’ service.  I have reviewed your query and here is my advice. There is a chance of the pregnancy because there is penetration of penis inside the vagina. Precum enter into vagina unknowingly before the ejaculation and precum contain sufficient sperm concentration that cause pregnancy. I would suggest to wait for the period.If your period will delay by more than 7 days then go for urine pregnancy test and or blood HCG to confirm the pregnancy. If you will be pregnant then you can terminate the pregnancy by abortion pill containing mifepristone and misoprostol under the supervision of the gynecologist.Hope this may help you. Contact further if follow up needed.Best regards,Dr. Sagar </s>
