Hello doctor, I don't want to terminate my pregnancy on internet but I just wanted to ask you till when I can terminate it by medicines?

Depends. It sounds as if you're asking how late in a pregnancy can you have a medical abortion. I'm thinking this is your question. If it's not consider rephrasing. Medical abortions can be performed between 49 and 72 days passed your last menstrual period. Most common is to use two medications, Mifepristone and misoprostil.
