Nausea before missed period?

Ha

Has anyone who has been pregnant before experience nausea before a missed period and been pregnant?

Back story-I’ve been pregnant once and had horrendous nausea and vomiting the entire time, but it didn’t start until about a week or so after I missed my period.

I’m wondering if my body knows what’s up and is now reacting to early HCg. It’s too early to test by maybe 1-2 days though 😭
