The reality star, 38, took the selfie at home while wearing grey underwear and posing in her dressing room.
She has been regularly updating her followers with her pregnancy journey and previously shared another snap taken at 34 weeks pregnant.
Journey: Nadia Essex showed off her blossoming bump as she posed in her underwear to mark turning 37 weeks pregnant on Instagram on Thursday
In this one, she wore a red bra top and black underwear as she no doubt looked forward to the future.
Nadia has been talking about her pregnancy journey with OK! magazine and has a podcast called The Clueless Mum.
She said: ‘My March due date is fast approaching so I thought I would share my birthing plan. Although I know 70-80 per cent of plans don’t go to plan, so I am fully prepared that it’s unlikely to be exactly like this.
Keeping her followers up to date: Nadia also shared these snaps of her tummy three weeks before
‘Stay at home playing games, cooking and having a bath for as long as possible or until waters break or four contractions in 10 mins.
‘A water birth, but not get into the pool until the pain starts to get unbearable. Water on the warmer side. No lukewarm/tepid water, so continued top-ups. Eating and drinking throughout. Massage.’
Nadia is due to give birth to her son in March, after announcing her shock pregnancy late last year.
She has documented the experience, from being informed she was a so-called geriatric mother to the terror she felt at an ultrasound, when she was convinced she had harmed her unborn child due to careless nutrition.
Honest: She told MailOnline recently that a routine midwife appointment struck fear in her when she was told her baby bump was ‘way off the scale’
She told MailOnline recently that a routine midwife appointment struck fear in her when she was told her baby bump was ‘way off the scale’.
She said: ‘I hadn’t seen [a doctor] in eight weeks and didn’t have a clue if everything was okay. You hope for the best but as a first time single mum, two whole months of no check ups seemed a long time.
‘I went for the midwife appointment and we listened to the heartbeat. That was all good. Then she measured my bump and I was way off the scale.
‘She was worried this meant I had gestational diabetes which could result in stillbirth. I have never been so scared.
‘I thought It was my fault and that, because I had eaten s**t, that I had given myself diabetes and potentially put my baby at harm before he is even born. I felt like the worst mum in the world. The worst human being in the world and cried solidly.’
Nadia’s concern was placated when she went for a follow up scan and the baby was measured.
‘It was all okay. He weighed well and there was no extra fluid which usually indicates gestational diabetes. I have to have the glucose test to double check.
‘Also, the baby is breech so I have to go back to the hospital in the new year to be monitored. It’s a lot but the relief that my baby is okay was the happiest day of my life.’
Nadia said that the worrying ordeal has only helped her take better care of herself.
‘It has given me the kick up the butt to get my nutrition on track. I have been craving nothing but sweet things and it’s time to get myself sorted as it’s crossed a line into gluttony I think.’
