Y’all is this normal?

I am in the medical field, so I FULLY understand that I need to get this looked at. My dad was in the hospital for chest pains last week, so I get it.

But I’m looking for validation that I’m NOT crazy. Isn’t it true that in pregnancy you can have palpitations due to increased blood flow/extra work on the body?

I’m 10dpo.. my period is due in 5 days. I didn’t think anything of this.. I’m trying but not forcing to get pregnant. I have subtle cramp, sore back, large awareness of my boobs... and now heart fluttering or skipping a beat?!

What’s the deal?! I’m trying so so so hard not to symptom spot 🤦🏻‍♀️
