Put ice over the fractured rib. Apply an ice pack, frozen gel pack or bag of peas from the freezer onto your rib injury for about 20 minutes every hour you are awake for the first two days, then reduce it to 10 â 20 minutes three times daily as needed to reduce pain and swelling.
1 Oral progesterone, such as Prometrium, is a natural form of the hormone used to help supplement the luteal phase during fertility treatments such as intrauterine insemination (IUI).  Progesterone suppositories, such as Endometrin and Cyclogest, are made of natural progesterone and are inserted into the vagina.
Progesterone (or sometimes dydrogesterone or hydroxyprogesterone caproate) is used for luteal support in IVF protocols, questionably for treatment of recurrent pregnancy loss, and for prevention of preterm birth in pregnant women with a history of at least one spontaneous preterm birth.
