If you have low levels of progesterone, it may result in a miscarriage, hence doctor may advise you to take oral tablets or the injection version. For me, I had to take both - progesterone tablets every day and 1 injection per week. It definitely helped to stabilize the pregnancy as I'm considered high risk, plus this was my 3rd pregnancy after 2 previous miscarriages. It's best to take if advised by doctor. All the best to you!
