I had to do the 3 hour test and they just told me to come back when ever I could and I told them when.
I did my 3 hour test at 30 weeks. I wanted to wait until after i had my shower to enjoy the food :)
Try not to put it off for very long if you fail it...It's important to know whether you have it or not and to take care of it if you do.
Okay thank you ladies I just didn't want them to schedule it awhile I'm away because I would be there for 2 weeks lol
