Palpitations? Pls help!

Ok so long story short, I'm a 23 year old female, healthy as far as I know, I just had my second baby about a month ago. Between pregnancies I developed anxiety and I would rarely get heart palpitations. During my second pregnancy towards the end I was having numbness and tingling feelings along with palpitations & flutters. I went to a cardiologist to find out I have two trivial leaky valves. Mitral & tricuspid regurgitation. But trivial. My ejection % was 65%. I have also been anemic this pregnancy. Now I'm 1 month post partum and all day today I've had a weird palpitation feeling. I feel like my heartbeat & the "skipped beats" are in my throat . Or like upper mid chest by my throat. I was laying in bed with my baby and had to sit up really fast due to a skipped beat & then felt short of breath. It's so scary I don't know what to do. My last echocardiogram (which showed my regurgitation) was about 2 months ago. They never said anything about a follow up. I need advice
