Slightly low heart rate

Elyssa

Hi all! So yesterday I went to my first US- based off of my lmp, I would have been around 7w5d but the baby measures 6w2d. Hoping I just ovulated later than I thought? Other thing was the heart rate was 91bmp. It was so teeny the tech said she thinks it’s a bit higher but her system could pick up on it (idk if that’s possible but you better believe I held onto that lol). Spoke with my doctor today and she wants me to get another US in 4 weeks due to the low HR But based off of everything else, she’s optimistic. I’m trying not to stress out, this is my first pregnancy and just want everything to be okay, ya know? Anyone have any similar experiences that turned out just fine? ❤️🤞🏼
