Hi S.,
I went through the same thing for two pregnancies. The first time that this happened, I unfortunately had to have a D&C at 10 weeks. The fetus was not growing at the normal rate and the heart had stopped beating.
During my second pregnancy, everything started off the same way as the first. I decided to seek a second opinion because our insurance company did not cover the suppositories and they were a little over $90.00. We opted to see a new OB/GYN closer to our home since it could have became a difficult pregnancy. My first OB/GYN had been practicing for many, many yrs, and was an older MD. My new OB/GYN is young and had actually just written an article on the topic. I was informed that unfortunately, it is actually up to your body to determine how much progesterone is produced. If it does not produce enough on it's own, then there is a specific reason for it. He advised me to stop taking the suppositories and wait it out to see what happens. After talking it through, we decided to take his advice, since the first time around, it did nothing for us. Guess what, my body produced it on it's own, it was just taking it's time to do so. I can however tell you, that the first 9.5 weeks were exactly the same, so we thought we would have to go through it for a second time.
My son was born at 38 weeks weighing 6lbs3oz and 19 1/4 inches long. He is now 37.5 in and 32lbs at 2.5yrs old, pretty healthy if I say so myself. ;-)
**Note: Insurances really do not cover progesterone suppositories because there is not enough research available to prove that this helps to keep a pregnancy viable.
Hope this gives you some comfort. Best of luck and congratulations.
