'We’ve gone to the doctor now three times and we’ve checked blood work and everything and everything looks good, so we’ve been very cautious as to when we were going to announce. We feel like we’re in a very good spot,' she added.

However, the Winning Balance author still finds it a challenging time.

'I want to be so excited and I am, but I’m also just very realistic that things can happen, and I’m just kind of taking it one day at a time,' she said. 

'I know God’s got a plan for us.'

In a series of videos posted to Instagram Stories, Shawn hinted that she had been 'keeping a pretty big secret' from her followers and urged them to check out their YouTube video detailing their journey and how she told Andrew they are having a baby.

'It's been a long one considering two years ago we lost our baby, and we have been blessed with another,' she said. 

The YouTube video was filmed on February 17, and at the start of the clip Andrew holds up a positive pregnancy test for the camera to see. The football player and his wife then look at each other and kiss.

'We are pregnant!' she says.
