I had taken pills for abortion in the month of Oct 11. After that twice, me and my boyfriend had unsafe sex, so can u please tell me that is there any possibility of getting pregnant?

Yes, there is a possibility.

Please use protection every time you have sex; there is always a risk of pregnancy when you are unsafe.

Don't know if the abortion was due to an unwanted pregnancy or because of a health concern that caused you to come to that decision, but anytime you have sex there will be a chance of pregnancy... even more so when you are not using protection. If it was due to an unwanted pregnancy, think very carefully about what you are doing and the risks involved. Your future health can depend on it.

Birth Control is a wonderful thing. If you don't like pills, or condoms, there's other ways.
This of course, assuming the abortion was due to unwanted pregnancy.
Please be careful.
