Is this normal in pregnancy or not? Besides feeling nauseous and tired with my first pregnancy, this one really takes they cake. This is my resting heart rate, or doing light chores. I only saved the bad readings, so it's not all day. Just happens randomly. My doctor put me on a low dosage of Zoloft for anxiety and she also said if I'm worried about my heart, she can schedule an echocardiogram. What do you ladies think? I'm 31 weeks pregnant.
