I'm 5 weeks pregnant for info.
I have a ridiculously high resting heart rate. It's over 100 bpm most of the time.
My pulse is so strong you can see it in my tummy.
I sometimes get lightheaded and my hands have a very faint shake.
My blood pressure is slightly high and has always been like that.
I'm relatively fit (walk 2+ miles a day) but a wee bit overweight.
Dr Google is suggesting Hyperthyroidism or anemia?
I'm worried how either will affect my pregnancy 
Does anyone have any experience of similar or advice?
Tia.
