Is a high progesterone in early pregnancy most likely due to clomid or multiples?

High progesterone is normal in pregnancy, it is just an indication that this is probably a healthy pregnancy. Progesterone levels are not related to multiples & also not affected by the Clomid you took early in your cycle. Congrats!

Your HCG level will tell if there is more than one. For 13dpo and HCG of 128 is great for one. My hcg for 14dpiui was 314 and the nurse said that this may or may not be multiples

Actually HCG levels do not indicate multiples. There is a large range of where HCG can be at a certain stage in pregnancy so there is no way of knowing by HCG level if this is a multiple pregnancy. I have seen women with twins have lower levels than those with a singleton pregnancy. This is a common misconception. The only way to determine if there are multiples is by US to see how many sacs are developing & you are too early to have this done.

Thank you for the input. I do understand the only way to know for sure is ultrasound. My question is because my level is higher then expected for my stage of pregnancy (upper limit of normal on my lab's assay for first trimester is 42). Women with multiples do tend to have higher levels of progesterone than singleton pregnancies (this has been shown in multiple studies). Clomid does affect your progesterone b/c it induces ovulation which in turn causes your body to secrete more. My question for the doctor is because of how much the level increased between 5dpo and 13 dpo to an above normal range is this more likely due to a lingering effect of the clomid or multiple pregnancy. HCg levels do not tell one for sure whether one is carrying multiples or not but just like progesterone they do tend to be higher and rise faster in twin pregnancies. I know ultimately I will just have to wait for my u/s but I was curious to get the docs opinion on my chances.
