Lots of my clients have pregnancies throughout their IVAs, and I have never personally experienced the loss of a case as a result of such a happy event in a client's life.
What I do with my own clients is work out a future fundsflow statement which takes account of the loss of income due to maternity leave, but then takes account of the child benefit and tax credits you may be entitled to as well as the additional household costs relating to the little one.
If you intend to return to work in the future, this is also factored in - so creditors may be asked to accept reduced payments for a short period, which can then be increased again once you return to work - obviously providing for any childcare costs.
You cannot put your life on hold simply because you are in an IVA, and most people do manage to work through their repayment programme with the assistance of their IP and the understanding of the creditors.
If you do not intend to return to work, that could jeopardise the future of the IVA.
