Resting heart rate

Mi

I know it’s normal for your heart rate to increase... but my resting has gone from avg 62 to 79! Is that normal? I will talk to my doctor about it tomorrow. I don’t feel short or breath... but I def feel like my heart is racing all the time. I have pretty bad nausea and water aversion so I’m not drinking my usual 150 ounces... but I’m not barely drinking either. Anyone else track and their heart rate increase?
