I have missed my periods but don't want to be pregnant

Why do you have unprotected intercourse if you don't want to be pregnant? Why do you let him ejaculate in you if you don't want to get pregnant? I know, you will say that you are using contraceptive pills, but did you know that they are not 100% sure? None of those are. Anyway, the only thing that I can suggest you is to take a pregnancy test and to visit your doctor for a blood test. If you have any similar doubts, you shouldn't hesitate to visit your doctor and ask him whatever you want to know. I hope it helps. 

I would see a doctor about this. Still, don't abort as many women have come to regret it. Also, be careful around contraceptives, as they have been classified by WHO as a group one carcinogen (cancer causing substance) Also, they usually fail.

I suggest you to have a pregnancy test first, if it comes positive  then you can have an abortion pills upto 10weeks of your gestational period.MTP Kit which are most effective medicines to abort unwanted pregnancy, it contains two pills Mifepristone and Misoprostol.
