Pregnacy symptoms after abortion

I had an abortion last week (due to Hyperemesis gravidarum) I had severe morning sickness and couldn’t even keep water down. I lost 5 pounds at 7w. My symptoms went away immediately after the surgical abortion. However today (exactly a week later) I’ve been experiencing morning sickness and constipation again like when I was pregnant. Is there any reason why I’d be experiencing symptoms again?

Sorry if this is the wrong group
