Hello doc. I am 21 years old. I had my period on 13 march. Today i.e. On 17 march I had an unprotected sex with my bf. Today was my 5th day of period. But their is negligible leakage. I had my last period on 8th of February and it ended on 11 feb. We did sex twice today. On the second time my bf left his semen inside me. According to him only 4-5 drops came out. Because usually on second time of sex, very less semen comes out. We had did sex earlier on 3rd march. I am worried if I would get pregnant. Are there any chance of getting pregnant. If there is any chance then what should I do to stop it. Pls help me. Thank you.
