Just started my second trimester yesturday😔

00
I had really bad gastritis and nousia from my 7th week - 10th week. For like 3 weeks I've felt great just a lil tired and need sleep during my day. BUT, I feel like my nousia has came back, for three days now I've felt dizzy, weak, and randomly nauseous? Can all this come back for my second trimester too?  I started feeling this after Monday when getting all the blood taken out for all the baby's health tests. 😷
