Sickness in pregnancy, often called morning sickness, is very common, with eight out of 10 pregnant women experiencing symptoms.

But some pregnant women experience extreme vomiting and nausea, known as HG, which often needs hospital treatment.

According to the NHS, HG affects about one to three in every 100 pregnant women.

“My sickness started early on – from the second I knew I was pregnant, before I even took a test,” Ms McIntyre said.

“Around about six weeks, the morning sickness really kicked in. Every morning, I was up being sick. Everything I ate, I was being sick.”

The sickness became so severe that Ms McIntyre ended up needing repeated hospital treatment for dehydration.
