Pregnancy question

Sidney

Okay mommies I’m 36 weeks today and I’ve been getting this left tight chest feeling right where my heart is, and I feel like my heart is pounding a million miles per hour and I get super weak I only have it some days I thought it had stopped but it came back... I even faint sometimes and it’s a super scary feeling and no one can tell me what it is! Has anyone gone through this or can guess what it is?

P.s I have gone to the doctor and they say it’s normal with pregnancy but no one else I know is going through this but me and it’s really rough on me and my energy. :(
