Weakness normal??

I’m 5 weeks today and this past Thursday and Friday I had a tonnn of energy and deep cleaned my house like crazy. Moved a couple pieces of furniture (coffee table/console table). Today I did grocery shopping at 2 different stores. This afternoon I feel completely wiped out and my body feel soooo weak. Is this normal this early?!? Did I over do it?? This is my third pregnancy and I don’t remember being this exhausted and feeling this way this early. Thank you!
