How long will it last?

Erin
Second pregnancy and so much more wiped than my first one. More nausea, more everything. I'll be 13 weeks on Monday and I can't recall how long the crappy stuff lasts.
I know everyone talks about the 2nd trimester being better, but does anyone remember when that actually kicks in ? 😊 
I know I'm wrapping up tri 1 now but I'm still feeling like hell, when was/is it for you guys?
