melster - congratulations also! i have read that more symptoms mean higher hormone level, but i had a high hormone level for my BT's and had no symptoms whatsoever - so i think you are right, its different for everyone. sounds like you are a person that gets symptoms straight away, which i would find very reassuring. at my dating scan (around 6 weeks & 4 days) i saw a fetal pole and heart rate was 119. i was worried it was a bit low, but assured it was fine. i was told they only worry if it is lower than 90bpm at that stage. at 9 weeks heart rate was in the 150's, then at 12 weeks it was 172. all the best.
I havent posted in here before, but I wanted to thank you for posting this info! I had my dating scan on Wed and was dated at 6w4d with a heartrate of 119/120 and was stressing because it seemed a little low. Feeling SO much better now though.
