I had a perfect pregnancy with my first ds, now 19.
Three years later, I had a miscarriage.
Got pregnant again almost immediately -- started having heavy bleeding at six weeks. Had an ultrasound every other week for several weeks. Doctor thinks the pregnancy was originally twins because there was a second collapsed sac visible on ultrasound. Once my doc decided the baby was viable, I took progesterone shots.
Decided a third child would be wonderful three years later, but it took well over a year to get pregnant. Miscarriage a couple days before what would have been my first ob appointment.
Younger child started kindergarten, and DH and I decided two children were really plenty. A month later, I found out I was pregnant with my third. He was born on my 38th birthday and is 9.
My 19-year-old and 9-year-old are best friends.
