Thanks for using the XXXXXXX I am happy to address your questions, changes occur in circulating blood volume, peripheral vascular compliance and resistance, myocardial function and contractility, heart rate, and sometimes heart rhythm and the neurohormonal system. The plasma volume increase is proportionally greater than the increase in red blood cell mass, and the resulting hemodilution explains the so-called ‘physiological anemia of pregnancy and causing a sensation of lack of blood supply to the brain causing sleepiness. During pregnancy, there is a fall in systemic (peripheral) vascular resistance beginning in week 5 of gestation with a XXXXXXX between weeks 20 and 32. It can also be anxiety issues (especially with all the anxiety associated with pregnancy). But may be that you might want to ask your clinician about and see if it is anxiety related or even panic attacks which can literally feel like a heart attack or cardiac related. Hope I have answered your query. If you have any further questions I will be happy to help. Thanks
