Increased heart rate in early pregnancy?

This is not my first rodeo, as this is my third pregnancy, but only second potential baby. I am only four weeks but the last couple days since I found out my heart rate has been about 15 beats higher per minute. I’m normally at a resting heart rate of around 85 and I’ve been at 100 or sometimes 110. Is this normal?

Now I have been stressed the last few days and anxious and scared about this pregnancy as my last one was ectopic and I lost my tube.

Just need some reassurance this is normal

Thanks!!
