Ultrasound can tell us a lot about a pregnancy, but it’s not always perfect. This is particularly true in the early months. Though it is rare, it is possible to have a “hidden twin” who is not visible during early ultrasound screenings. Nearly every pregnant woman considers the possibility that she may be having more than one baby. Whether it is due to signs or symptoms that point to twins or just a hunch, the thought probably crosses everyone’s mind at one time.
The only way to confirm a twin or multiple pregnancy is by visually identifying the multiple fetuses with ultrasound. If your doctor or caregiver can only see one baby, it is not likely that you’re having twins or multiples. While a decade or more ago it may have been easier for a twin to “hide,” today’s imaging is far better and allows doctors and technicians to get a clearer view of the womb. After 20 weeks, a second fetus should be clearly visible on ultrasound.

Ultrasound provides a picture of the womb, but sometimes the picture can be misleading or misinterpreted. Chances are, you are not having twins if there is no evidence of multiples on ultrasound.

At pm our sweet Oliver was born at g, shortly followed by his sweet little brother Riley weighing g born three minutes later at pm.

Then off went dad and babies straight to the NICU. I was talking to him about my recovery and he was sending me a photo of my babies?!
