Progestrone? Should i talk to my doctor about it?

After suffering two losses in early pregnancy over a year ago, my OB is finally going to start me on Clomid. However, should i talk to him about progestrone suppositories? Is that something that is harmful if you do not have low progesterone? Im terrified of another loss and i still have to complete an ultrasound of my ovaries and one more round of bloodwork before starting clomid. Is the progestrone something that is always given to women who are using clomid to become pregnant? Would just love to know if this is something worth asking for! Currently TTC for 16 mo, 2 miscarriages, and irregular periods (50+ days apart with barely any positive OPKS)
