So had my 12 week scan yesterday and luckily there seemed to be a happy baby in there plus an enormous fibroid. I had a private reassurance scan 2 weeks ago where it was first detected, but they measured it as 5x5 cm. Yesterday the sonographer was having trouble pressing down on my stomach huge so went looking for a fibroid. She tried to reassure me that they probably got the measurements wrong at the first scan. You can actually feel it by pushing lightly on my stomach. As I've suffering from slow gut transit since being pregnant, I always thought the lump in my abdomen was poo. Doh! I'm really worried about it getting bigger as my uterus has already extended further into my abdomen than it should at this stage. I've been referred to a consultant so they can monitor the situation.What are other people's experiences? Will it shatter as the baby gets bigger?
