Jul, don't worry too much, might be low iron. I am taking multi-vit Blackmore Pregnancy & breastfeeding Gold (comes with fish oil and iron)and Calcium.
Pegsfur, my friend over here got G. diabetes during pregnancy, she is just 28 and she has to go to dr very frequent for check-up and sugar test. She was place under high-risk so her diet was being control too. She told me if not it will not just affect her and her baby. So please do not take all those gassy soft drinks and try to drink as much water as possible and maybe a possibility to watch your diet like cut down on carbo as they will change to sugar in the body and not used to fat, try to eat more vegetables and meat with low fat.
PJPJ & Pink, like what I have said before, Oscar, blood test might be the statistics and it is not the final verdict yet. Pray and talk to baby, dr already asked you to do the amniocentesis which is diagnostic which is 99.9%.
For me, being a christian, I strongly believe in prayers and that God desires all of us married women with healthy and lovely children and that prayers change things and Jesus can heal and perform the miracles in the past, He can do it now and in future, just that we have to believe wholeheartedly when we pray.
