Congrats on the wonderful news, Starry Night, that's awesome!
So I had my scan this morning. They took forever taking all of the pictures, but finally told me that baby is perfect (they were doing an echocardiogram because of the Lexapro I was taking early in pregnancy) and everything looks great with him. He's measuring right on schedule!
The doctor came in and spoke to me. He called the area of blood a placental lake, rather than a hematoma. It was on the surface of the placenta, near the cord insertion. The tech couldn't measure it because apparently it kept changing shape (?), but from one measurement she tried it was 3.5 cm by 1.2 cm, so it didn't seem huge. It looked exactly the same as it did 2 weeks ago, actually. He was super, super laid back about it, said that it shouldn't cause any bleeding or problems at all. He told me that I didn't have to do anything differently, be on pelvic rest, etc. I'm going back in a month for another scan, but he told me if that scan goes well that I will be fine to go on the road trip/anniversary trip that DH and I had planned for April a while back.
So basically, I'm happy. Baby is perfect, no problems, and the doctor didn't seem to think that the lake was an issue. I am confused, however, with the difference between a placental lake and a preplacental hematoma. I asked if the fluid was blood to which he replied "I don't know, we'll probably never know"...
But I didn't see a difference appearance-wise between the fluid on my placenta and the images I've seen of preplacental hematomas, so I don't know how he distinguished the two. From what I've read preplacental hematomas tend to be near the cord insertion, which mine was. They are on the surface of the placenta, which mine was. So how does it differ...? I wish I had thought to ask!
Still, happy day!
