Anyone's pregnancy pains getting worse going into the second trimester?

me

I'm 11 weeks right now and since maybe 3 weeks ago, I feel more exhausted, more nauseous, I'm having more pains in my stomach and just having a hard time completely.

I'm also just very faint and having horrible nightmares so I'm not sleeping well.

I'm not sure if this is normal since most women say the second trimester gets so much better, but I feel I'm getting worse? Anyone else?
