I know exactly how u feel! My DP at the time (now DH) and i hadn't been together for very long when i found out i was 4 weeks preg it was such a surprise to us both and he was in victoria i was in sydney so it was hard to come to terms with!! I was pretty anxious and scared thru the pregnancy but excited expecially when my DS started kicking and moving around and every night without fail he would get hiccups not long after i got to bed and i would watch my belly move up and down! He is almost 3 now and i woudn't swap him for anything!!
Best wishes for a healthy and happy pregnancy! Isn't it amazing watching them on screen in an ultrasound? I go for my second ultrasound in a few weeks for baby number 2 and can't wait!!
