Lack of Symptoms

Hey Everyone, I'm currently 17w3d and I've noticed that my symptoms have pretty much stopped :/ my energy levels are rising and my appetite is slowly coming back. But my sciatica has pretty much subsided, I'm not really feeling any round ligament pains and my sleeping has gotten better. (My main symptoms were the sciatica, round ligament pains and lack of energy and appetite) my pregnancy has been so easy and I'm so thankful but I just can't help but worry. Has anyone else experienced this?
