Progesterone for baby number 2

Hello everyone, it has been awhile since I have been on this site. Haven’t been on since my daughter was born in 2018. We are trying to convince baby number 2 the Dr told me I would probably go on progesterone shots to help prevent pre term labor since my daughter was born at 34 weeks 5 days. Just wondering if anyone has had to do them and if it helped keep baby in longer. Thank you :blush:
