Beta, the body is carrying extra weight and blood, so heartbeat can go up. Sit calmly, drink a glass of warm water, and avoid stressful thoughts, but do let your doctor know on your next visit.
My saas always told me to sit down immediately if I felt my heart beating fast and drink some coconut water. The doctor also said it's common due to extra blood flow, but suggested not to ignore if it happens too often.
I felt my heart racing so fast sometimes, especially when lying down, and it really scared me. My doctor explained it's just the body working extra hard, but please tell your gynac if you feel breathless too.
I completely panicked when my pulse crossed 100, but my gynac reassured me it's totally normal as our cardiovascular system changes so much. Just rest often and don't panic, but keep tracking it.
During pregnancy, your blood volume increases by almost 50%, which naturally makes the heart pump faster. However, it's always best to get your pulse and thyroid checked by your doctor to rule out any other issues.
