Hi All I am also due in March, 21st and its a second baby for me already have a toddler so I am shattered more this time round and feel more sickly! I had a dating scan yesterday could not see a lot but saw the tiny heart beat and thats good enough for me! I just wandered, do any of you have an under active thyroid as I do and I am having my levels monitored and it can be serious in early pregnancy. look forwards to hearing from someone soon.
