Week 21 is coming to an end, tomorrow I'm going for an ultrasound. I feel great, but why is it always so nerve-wracking ? I hope everything is going well ??? By the way, girls, how much have you gained by 21 weeks? I've only gained 2 kg so far. In my first pregnancy I was already +5 at this point. Overall, I gained 10 kg during my first pregnancy — I hope I don't gain more than that this time ))
