Should I be concerned?

So I am 27w5d pregnant and my resting heart rate was just at 140 (I manually checked). I have been in bed all day due to menstrual like cramps and an awful headache. My chest feels tight and it makes it feel hard to catch my breath. I know that an increased HR during pregnancy is normal but before, mine was in the high 70s to low 80s. Should I be concerned?
