Pregnancy Reduced movement

At what time do you start to worry?

My cousins pregnant 7 months and we’re super close spent most days together since we was baby’s.

Her baby boy hasn’t really been moving since Friday, yesterday she only had a tiny bit of movement in the morning nothing since then and today nothing at all either.

What can we do to get him moving ? And at what point do you worry?

( she’s also had a tiny bit of bleeding when she wipes when she goes to the toilet is this anything to panic about with the little movement ? )

It’s her first baby and I’ve never been pregnant so we’re not really aware
