For my 7 week ultrasound I made myself so unbelievably sick because I was so worried. It was my worst day of MS through the whole first trimester. I was soo worried it would be an ectopic preg.

Come my NT scan I had done it again, I find myself getting very anxious about U/S and I have had so many before (PCOS). I think it is the most worrying test (even though I hate needles I can handle them better then the Ultrasounds) because this is the time when they can tell you definatively if something is wrong - so I feel for you because I was exactly the same.

Come the 20 week scan I found that if I looked forward to something I would worry less. So look forward to hearing the heartbeat or seeing your little bub (look human for the first time LOL) rather then let yourself get too worked up. I didnt feel pregnant or look pregnant till about 16 weeks. Try not to worry - I know its easier said then done though.
