HELLOOOOO 2nd Trimester!!!

Hi everyone! I'm 13 weeks on Friday already!! Some questions for you ladies: I haven't been sick at all (thank God right!?). Did any of you not get sick til the 2nd trimester? Also, do these ridiculous emotions EVER calm down? My temper is stupid and I cry over literally everything. And finally, when did you start wearing maternity clothes? Thanks ladies!!
