Hey Lindsay! Congratulations!! What a shock huh? Too say the least!! I have twin girls too. My son was not quite 18 mos when the girls were born. So we are in similar boats. Hard to imagine 3 so close huh?
But yes as a poster said 2 placentas can defintely be EITHER id or frat. I am always amazed at the amount of moms who said their doctor told them it was frat because there are 2 placentas. It irritates me that a doctor gives out that kind of wrong information!! 1/3 of those babies are actually MZ twins!! That is a big percentage! So if their blood types are the same then go on to DNA tests if you want to know.
My girls are MZ but there was only 1 placenta. We didn't know for sure till they were born because there is always that chance that it was orignially 2 placentas that fused into one. But once it was examined after birth it was definitely one.
I wanted to tell you though that there are a few of us that have gotten preg with our MZ twins while nursing. I was suprised myself to know I was preg with one more or less two because I was nursing ds so much and only had 2 (sort of) periods. Karen (1plus2) I know had the same situation and she shared with me something she read about being low on calcium while nursing which may cause the egg to split. Interesting huh?
Good luck to you girl!! By the way I checked out your blog and saw your pics of you huge belly!! Man that brings back memories!!! It is amazing what your body can do!! Hang in there!
