Hi, I'm now 7 weeks pregnant and have been getting nausea and very tired often. Struggling most to not tell people I'm pregnant yet till we've had 12 week scan! Anyone any tips on how not to make it obvious to work colleagues when tired, eating a lot of breadsticks, trying not to talk about feeling sick and nipping to loo every two seconds?! Also, when did everyone else first tell parents? (First grandchild). Thanks.
