Crinone (progesterone gel)

Has anyone been prescribed Crinone (progesterone gel) to prevent pre-term labor. Did anyone else take this? It’s been prescribed to try to prevent preterm labor after first baby arriving at 35 weeks.

Can you let me know if it worked or didnt work for you? Looking for any input but am only finding feedback for people who used as a part of IUI or IVF so this situation is different. Thanks!
