What did you do when you first saw two pink lines on a pregnancy test? If your answer is "take several more pregnancy tests", you are not alone.
One in twenty women will take more than 16 pregnancy tests to determine if they are pregnant, according to a recent UK study.
Channel Mum found that seven per cent of mums will take 10 pregnancy tests, while, on average, women will take six different tests before accepting they are in fact pregnant.
But then other women anxious about the validity of the test or the longevity of their pregnancy will use home pregnancy tests as a way to reassure themselves.
The behaviour has been dubbed "pregnancy test addiction" by the parenting site.
It asked 1,435 mums about the use of pregnancy tests and found that one in 12 pregnant women continue to take pregnancy tests up until their 12-week scan.
So worried about the ongoing health of their baby, it was discovered 62 per cent of women will continue taking tests despite already having a positive result.
"Being hooked on pregnancy tests may seem strange, but the majority of mums do it," founder of ChannelMum.com Siobhan Freegard told The Sun.
"Seeing the positive sign come up gives mums-to-be a buzz and also helps reassure those who may be nervous about their pregnancy."
She warned Mums not to take too many tests.
"It's important not to get addicted to continual tests, as they are expensive and unnecessary," Ms Freegard said.
"We have heard of mums testing up to five times a day to check they are still pregnant, so if you are anxious, then get professional support."
While the study found that more than four in ten mums-to-be used expensive early indicator pregnancy tests, one in 100 also tried DIY tests such as mixing toothpaste or bleach with urine.
Then when pregnant, gone are the days of waiting until the 12-week scan. Many pregnant women are now telling family and friends way earlier.
More than half of women are sharing the news by the seven-week mark and one third are letting people know straight away.
And women are also moving away from the traditional methods of informing loved ones of their impending baby arrival.
Although 53 per cent still tell family and friends in person and one in five tell them over the phone, many are turning to social media.
Three in five people share the news on social media and 45 per cent share an image of their baby scan, while 20 per cent of mums-to-be announce their pregnancy on apps such as Snapchat and What's App.
