Next to the snap, Helen shared another of her hand holding an ultrasound picture while laying in a hospital bed.

In the post’s caption, Helen wrote to fans: “I’ve been a lot quieter on my social recently as I’ve had hyperemis gravidum.

"I had this with both girls but this time was on another level.

“I am so relieved to be over the worst and so very happy and so grateful for my baby.

“My mum has just been the best and I have no idea how I would have got through it without her!

“Scott’s been amazing with the girls and the nurses at the Royal Bolton Hospital were so lovely which I’m so grateful for. I just can’t wait to meet my little one so in love with them already”.

She then told her fans: “I’m going to film an IGTV on hyperemis soon and any other mummy’s to be with hyperemis I feel you x”.

Helen suffered hyperemesis gravidarum with both her girls’ pregnancies.

She previously opened up about it to Ok! magazine, saying: “I have just been really poorly.

“I couldn’t go into work and do any filming. I had hyperemesis gravidarum, it lasted for five weeks. It doesn’t sound like a long time but I was just so ill.

“Luckily it cleared up at ten weeks. I know some women have a horrific time and end up in the hospital for nine months, so I was lucky, but it was horrendous.”
