So i tested this morning after having aprego dream. The test had a default so I tested again. It came back + I'm so nerves we have a 9 year old two 6 year old a 2 year old a 5 month old and I'm due in Feb. We are excited since we have been trying again. But I'll also have 3 kids under 3 when this baby is born. We have decided not to tell friends and family til we know what we are having.
