Is it safe to take medical abortion? The last day of my menstration was December 10. As of now I can say I'm 55days pregnant.

What do you mean by "medical" abortion. Your doctor will determine if an abortion is safe or if you have any underlying health issues. If done properly the clinical abortion has very minor risk to the mother, assuming done in a proper licensed facility.

You're less than 2 months pregnant if you're at 55 days pregnancy. Is your pregnancy confirmed?

I'm assuming, by your limited info, that you're planning to take an abortion pill? Have you researched the side effects, the fact that it's not 100%? It's much safer to abort at a clinic, where they remove the fetus from your body. It's also easier on you if you choose that course.

Bottom line, even an abortion with the pill, needs to be seen to by a doctor. Have you discussed this with your doctor?

Do discuss your options with your doctor or at a pregnancy center. Generally a medical abortion will be done earlier in a pregnancy. You will possibly have a scan done since you are uncertain of how far along you are. A surgical abortion would be more likely to be recommended if you are as far along as you believe.
