Hi m 22 yrs old. I had unprotected sex with my boyfriend on the 4th day of my MC last month i.e. 12th may. I took a contraceptive and got down again after 5 days i.e. 17th may for 2 days. Its 9th June today and m not down yet. Could I be pregnant?

Since you have had sex, unprotected at that, than yes, you could be pregnant. Wait another week and see if your period shows up. If not, try a pregnancy test.
