Kellbell-I understand your worry believe me every scan i went to i was sick with anxiety leading up to it after all Abbi's scan's were abnormal and they would find something else wrong each time we went.
But you have had no problems so far your ealier scans were all good weren't they? so try to relax there is nothing you can do until you get in there and they have a look so dont stress it will only make things worse and bubby needs a calm mum.

Forshelby-sound's pretty normal to me our stomach muscles stretch to all buggery when we are pregnant and any extra pressure on them can make them sore i know when i work my stomach is extremely sore by the time i get home all the bending and reaching really does a number on mine to the point that no position is comfortable and i feel like i have torn my muscles so i have to take panadole then it comes good the next day only for me to go back to work so i am trying to do a lot of my work standing to avoid all the reaching and stretching.

Angelfish-It is hard with DP kid's but when you have your own baby you will understand the bond between a parent and their child and that is something you will never have with his kids that unconditional love and when you have your little one you will see what i mean imagine the shoe being on the other foot they were your kids and he wasnt to keen on them and didnt want them around so often it would be hurtful to you i know what you are going through i have a step daughter who cant do any wrong in her fathers eyes but i deal with it in a way that make DH see they he is favoring her and he really tries to treat and disapline them all the same but as i said when you have that maternal bond there is just something there that the step parent will never have and when they do wrong let him deal with it so he can see that they are not perfect and he needs to pull them into line but just remember how you you love your DP and do it for him they are his children and he will always love them so they come as a package deal and remember THEY GO HOME!!!! lol

AFM-all good with me my disco queen is kicking up a storm when she is awake and i have been buying a little every week to get ready for her arrival.
