Considerable time has passed since the positive test and the realisation you will be a parent, which should have given you some time to settle into the new reality.
The due date is closing in and many thoughts are likely circulating in your mind. Be sure to talk and share a lot of your thoughts with your partner. Also, listen to her needs and if you have any family members or friends you can confide in, now is the time to take advantage of the support system available to you.
Something that you can put down and plan for is purchasing. Have you looked into buying a pram? A car seat for the baby? Cot? Baby Clothes? It's easy to get lost in thought about things needed and the expenses, but with careful planning and the realisation you still have time on your side, it should all come together in the end.
