28 weeks today.... Hello 3rd trimester no matter which way you count it! Have my glucose test tomorrow... It's at 3pm and they told me not to fast (not that I think I could for that long) any suggestions on what to eat today and tomorrow to pass... i have a big sweet tooth and so does baby so I really don't want to have to give it up... and I aIready don't like having blood drawn and would prefer to keep it to a minimum haha...
