Suddenly feeling great?

Okay so I know you might think wow I wish o felt great but I am so confused and worried I might go into preterm labor. Today I noticed my baby had dropped and I feel like super limber and great. I slept amazing last night and feel like myself again like I was before pregnancy. I feel lightweight and it’s so much easier to breathe. Baby is moving great and that’s like the only way I remember I’m pregnant and that my clothes don’t fit. Other than that I have felt so great today. I’m 32 weeks tomorrow just wondering if anyone else has had this with their first baby. Or if I’m just having a good day? 😅
