Noise next door

Pip • Pregnant with a little boy • c-section is booked for 4th July 2016 at 8am ✨
The next door neighbour is making very strange noises. Can't work out if she's having sex with someone or is in pain. It's been going on for an hour now. Should I be concerned about her? Her husband and children are out. So if she is having sex then she's having an affair. But I'm worried incasr it isn't that, she's actually in the room and can't get up because she's in pain?
