It all depends if it's a medical or a surgical abortion. The method recommended for you will depend on how many weeks pregnant you are. A medical abortion is carried out using medication and a surgical one involves a minor operation. Medical abortions carry less risk and are easier but you can't get one if you are more than 4 weeks pregnant, then you have to go for a surgical one.
Surgical ones take much more time to recover. I had one years ago, (was 6 weeks pregnant) and It took me 3 months to recover (both physically and mentally). It does take a toll on your body, messes up with your brain and totally fucks messes up your hormones. You become a basket case for a month.
I'm not sure what's your situation but be ready to take at least 2 months off. Taking less time than that is crazy and putting your body's health at risk. Do not do it.
