I Am 8 Weeks Pregnant With Two Past Miscarriages At

I am 8 weeks pregnant with two past miscarriages at about 24 weeks and a premature birth ( she's now 9 years old) at 27 weeks. The doc put me on gestrone 25mg /1ml injection twice a week since about 2 weeks now. But a I saw another gynecologist today who recommended to stop the injections and start cyclogest 400mg twice a day. I am confused on the choice to make. To continue the injections or the cyclogest. I want to do everything to take all precautions. I waited a long time for this
