I hope you are feeling OK. Best thing you can try to do is just relax. I am 34wks right now with pregnancy no. 9 I have just 1 DD who is 8 and it has taken me this long to get this far. It is different everytime for everyone. But my best advice is take it as easy as you can, try to relax, don't count your chickens yet and take each day as it comes.
I never had any tests on my lost babies either, I just felt like I did not want to go down that path. Nosleep is right, what will happen will happen especially as it is still early. I have beaten myself up so many times and tortured myself through early pregnancy. With this one I took it really easy and if I am honest tried to not even think about the fact that I was pregnant until after 12 weeks. In the past I had been to the Early Pregnancy Unit and been scanned and monitored early. All it did was give me false hope and stress me out. This time I did not go to see them until I was 13 weeks and I knew that he had a much better chance to go the distance.
Feeling bloated, having trapped wind, feeling sick in the early days are quite usual. With this one I felt AWFUL for the first 4 months. Bloated, sick (I suffer from gallstones as well and do not think that helped) Please please do not examine every little thing your body does and look for an answer. Be good to yourself, look after yourself, eat well, take your prenatal vitamins, and REST UP. Allow yourself to be strong and to love who you are, whatever happens you need to look after yourself as best you can and not beat yourself up. Anything you can do to relax yourself and chill is great.
Huge hugs - I know just how you feel and you will get there, just give yourself a break xxx
