Hello. I am 36 and have three older boys. We decided to try for number four almost two years ago now. It took quite a few months but we got pregnant in Jan of last year. Sadly that ended in mmc at 12 weeks. We had a chemical two months after that and then got pregnant again the month after that. That also ended in a mmc at 13 weeks. We decided to try one more time and got pregnant 8 weeks ago. My progesterone was low this time so they put me on progesterone 200mg once a day vaginally. I didn't notice much difference the first week of being on it, but starting the second week my bp began going lower and lower to about 100/65, which I know can be normal, BUT my heart rate has been going lower too. It is usually higher around 85-90 but the last few days it's been 60-70. I know that 60 is still within the normal range but shouldn't my hr be going up during pregnancy? Just wondering if anyone else has experienced this? I have looked all over the internet and can't find anything about progesterone lowering hr and bp....
