Heart worries

I've been having heart palps since becoming pregnant. A month ago my doc said he would monitor me at my next appt if it was still happening (thankfully that is tomorrow morning) because they are very frequent. Sometimes I get spells where they happen once a minute. I get light headed easily these days and have frequent headaches. Just now I used my fetal Doppler machine to hear my own heart and it averaged 96 bpm resting. I am scared there is something wrong with my heart. Babies heart beat is always around 150 so that's good. Praying for good news tomorrow!
