Increases nausea at 12 weeks

I thought my nausea had FINALLY gone away around 10 weeks, but as soon as I hit 12 weeks, it came back with a vengeance! I’ll be 13 weeks tomorrow and it’s worse than it’s ever been. Has anyone else experienced this? I thought the nausea was supposed to subside the closer to the 2nd trimester, not get worse 😭😭😭
