Symptoms disappear at 12 weeks?

Anyone have symptoms go away at 12 weeks? With my first pregnancy i was so sick most of it so i can’t really remember when symptoms stopped. But my nipples are way less sore than yesterday. I’m on medication for my HG but I’m way less sick then i have been this whole pregnancy. Earlier today i was cramping so bad that it wrapped around my back. But it stopped after i laid down and drank water. But there was no bleeding. I’m really scared because i don’t want to lose my baby but idk why my symptoms would disappear so abruptly
