"Identical twins develop when a fertilized egg splits. Depending on when the split occurs will determine if the twins share a placenta, with either one or two chorions and amnions, or if they each develop their own placentas. In general, the later the spit occurs, the more likely that the twins will share one placenta."
Why did I copy and past that from a medical journal? Glad you asked. I have been furiously scouring the Internet (trying my damnedest to stay away from the forums) to find info on identical twin embryology and vanishing twin syndrome. The research I've done makes me feel much better about what I'm experiencing now. Women can have full on clotting and cramping when losing one and the other is perfectly fine. Hard to believe but it's true. The scary part I ran across was that with some identical twins if one triggers the mothers body to miscarry they both go. The reason is the shared sac and placenta. I never knew this but depending on when the embryo splits determines if the babies will be in one sac or two. I'm relieved because my two are clearly separate w/their own placentas. That way if I do lose the one that "doesn't look good" their brother or sister doesn't necessarily get expelled along with it. I realize this is a negative and dark post but in all honesty it is hope for me. This is a ray of sunshine and I need it.
Today marks 6 weeks. Lots of growing and developing is happening. Nose, mouth, ears, arm and leg buds are all starting to protrude. The heart is beating about twice as fast as mine. Trying to focus on what is most likely happening. I am still experiencing the same symptoms. Heartburn is worse now that its accompanied by acid reflux but I'm thankful for anything that makes me feel pregnant.
Nurse Marty called to check on me this morning. It was mostly her reassuring me that this is super common and again was to be expected base on the ultrasound. Spotting has lessened this morning so clearly I'm hoping that it goes away completely before I go back to work Sunday. Regardless I figure I'll be wearing the phonebook pad until my next ultrasound!
