So I've heard of resting heart rate increase can be a sign of pregnancy. I track my resting heart rate with my Fitbit. I noticed that it's been just shooting up fast. I haven't done anything different. The same thing happened back in may and I was pregnant. Unfortunately it ended up a miscarriage. I waited one cycle and now trying again. I'm going to test on Wednesday but I really hope it's a good sign

Just curious if anyone has experienced this before.
