High heart rate and dizziness

Ka

Hey fellow mamas, I wanted to see if anyone else was experiencing what I’m experiencing. I noticed just in the last week (I’m 6 weeks) that my heart rate jumps higher than normal a lot throughout the day (up to 145 bpm) and at that moment I will get dizzy, like I’m going to pass out. I have to sit and close my eyes until it passes. My normal heart rate is usually in the 70’s/80’s when it’s not jumping up. am going to contact my doctor but online all I could find was that it was normal. I didn’t experience this with my 1st pregnancy and it’s freaking me out and making work and being a mom extremely hard and emotional. (I work at a daycare with 9 — 14-24 month olds)

Thanks ladies
