Whatever your reaction, you may be wondering how this pregnancy will be different to that of a singleton. Here, NowBaby Mum Sharley shares her experience of a twin pregnancy, from finding out that she was expecting two, to the worries and complications of a multiple pregnancy…. Third time round I should know what to expect and know the signs etc etc right!? Well sort of but all those signs were… different, they were worse, more intense. My morning sickness was twice as bad and I seemed to be tired 23 out of 24hrs. I took my sister out for a birthday meal, she was 6 months pregnant at the time and we joked about how maybe rather than just me getting older and having two kids already having an effect on my symptoms that maybe I was expecting twins.

The day before I went for our 12 week scan a colleague at work cracked three double yolkers in a row in front of my eyes! I thought nothing of it as I had an 8 week dating scan which showed one perfectly healthy baby inside of me. Sh e stopped early in to it and looked at us cautiously. Naturally t hinking the worst. Picking up on my anxiety she quickly interrupts before I can say anything else and says “There is definitely two in there , but l et me just make sure there aren’t any more!

WOW, that is certainly one moment in my life that will stay with me forever. As I lowered back down and she proceeded to scan my belly the screen certainly did come to life, just a little more than we had expected. Two, thank god. Cudos to those out there with triplets or more!
