The 36-year-old star was reportedly under the close eye of doctors following pregnancy complications but is now said to be doing well.
"The visit is a normal thing for a lot of pregnant women and there is no drama," an insider told E!Online.
"All parties involved are healthy and fine."
As we previously reported, Reese was admitted to hospital with sources claiming she was close to giving birth. Her first child with husband Jim Toth is not due until early September.
The actress was said to be calm and collected about the pregnancy scare while talent manager Jim, a first-time dad, was reportedly a "bundle of nerves."
This will be the third child for Reese, who shares two kids — Ava and Deacon — with ex-hubby Ryan Phillippe.
