You sound just like me!
I am 28 and this is my first pregnancy, I have been wanting a baby for years and years, there was nothing wrong, we just though more financial stability would be better - HA, like there is such a thing! So we bit the bullet and jumped in head first, we got pregnant the second month!
So just like you I had REALLY been looking forward to this... I guess I had some vague notions of what was involved but I wasn't behaving in any of the ways I thought I would... I always believed having children was the most natural thing in the world, I mean people and animals do it every minute of every day - right?
Well, I couldn't believe the things that I was thinking and dreading... It felt like the most unnatural thing in the world! I thought I had an ectopic pregnancy, I thought I was having a miscarriage, I ate all the right vitamins but got back some bad blood tests so thought I had damaged the baby by my actions (dreadful guilt), then the blood tests were ok again, but then I was worrying I wasn't eating enough of the nutrients the baby needed in my diet without the vitamins, I read so much stuff and some of the warning signs were the same as the usual prenancy symptoms? etc, etc, I was so confused...
My best advice is to book in for the Nuchal Translucency Ultrasound at 11 - 13 weeks, not so much for the tests for down syndrome (which also puts your mind at ease) but more just so you can see your little jellybean - I absolutely LOVED it, I couldn't believe it was so developed already, with a cute little button nose! And I swear in the photo he/she is smiling at me! And I couldn't believe how much he/she was moving around in there - so I felt "surely somebody so active is going to survive the long haul"!!! And to see the heart pumping, well no words needed there...
And since then I just have this feeling of calm, knowing that everything is going to be just fine... I just look at that little picture on the fridge and have a giggle.
Like me, you may even have this scan before you have a check up at the hospital (I'm nearly 16 weeks and STILL haven't had my first general check up) busy at the hospital I guess...
You just need to go to any old GP and ask for a referral letter to the closest Ultrasound/Xray clinic asking for the NT scan and related blood tests, then call them at the clinic (number should be on the referral letter) and make an appointment - nobody told me this stuff so I hope it is useful to you?
