There is no standard definition of a pregnancy heart rate that is too high or too low. Instead, doctors look at a person’s baseline heart rate and how their heart rate changes over time. - google https://www.medicalnewstoday.com/articles/heart-rate-during-pregnancy#abnormal-heart-rate
yup. expect your heart rate to go up to 100s later on in preg as your body works harder to supply more blood to baby. :)
pulse rate is not enough to tell if pregnancy is going well. check with gynae
Yes. My gynae says baseline is 90bpm.
