Unusual first symptoms

I'm not too worried about it just kinda curious.

My cycles are wonky so not even sure when my period would be due (sorta irrelevant, but,). I'm about 10ish dpo and have had some heart palpitations for days now.

I did have them with my previous pregnancies but not until further along in the first trimester. Definitely not before a missed period.

I've been ruling out other factors and pregnancy came to mind, It's possible I did ovulate earlier than I think so who knows.

I have a pregnancy test at home here but am saving it for any more signs that may pop up.

Just curious if anyone has had heart palpitations so early on? Unusual first symptom? I have minor cramps so this can totally be period on the way. No biggie. Again, just curious about others experiences with heart palpitations.
