I am nearly 22w with twins. All has been fine so far. I am trying to stay active so do a gentle gym routine twice a week. While there I tend to hop on the scales, just to keep an eye. So far I have been gaining about 0.7kg per week, which afaik is nice and normal.
Then since last week it's stalled and I have dropped. Not much but from 70.4kg to 69.5.
I am using the same digital scales each time, same time of day, same clothing. I don't think it's an error.
Would that worry you? I just assumed I would be putting on weight at this stage, not losing.
