The Technical Stuff about Twins
Okay so here is some technical mumbo jumbo for those of you out there who are curious about what kind of twins I am carrying.
There are two types of twins monozygotic, which means from one egg or identical and dizygotic which means two seperate eggs or fraternal. We won’t know what type of twins I am carrying until after the birth and some genetic testing. Just because twins are labeled identical does not mean that they will look alike (strange I know) and it is common for fraternal twins to look more alike than identical twins (again, freaky).
Here is the good news. There are two more common ways to carry twins diamnionic/dichorionic and monoamnionic/monochorionic (mo/mo). Right now I am carry diamnionic/dichorionic (di/di) which means that the they are each in seperate placentas. Some of the books I have read say that means that they are fraternal and some of the books say that means you can’t assume that. The reasoning behind that is because mo/mo twins can split their placenta and look like di/di twins and di/di twins can fuse their placentas and look like mo/mo twins. The good news about us is that the diamnionic/dichorionic is the safest way to have multiples. No fighting over food and each has his/her own space (for now). Later on it gets pretty cramped in there and that is what leads to lower birth weights. NOTE: Fraternal twins can even have different fathers! Now that is freaky. I don’t mention it because it is a possibility in my case but just because it is interesting:)
A normal gestation for twins is 37 weeks, just 3 weeks shorter than the usual 10 lunar months for a singleton pregnancy (don’t I sound smart). So in reality we would be expecting a couple bundles of joy in January but that is okay cuz some of my favorite people were born in January. The official due date is still the first week of February. With the pregnancy I can expect to gain between 45 and 60 pounds! Good news is that not that I can eat without feeling sick my body is all about the fruit and is slowly coming around to the vegetables. So far so good on the eating front. I do eat a lot of popsicles but they are little and only 60 calories of the 3100 I have to eat a day and 131 g of protein (cripes!).
So now you all know when people ask if they are identical or fraternal you can say you don’t know but you do know that they are diamnionic/dichorionic;)
