Today I got my braces tightened and felt pressure but it didn't hurt. Does it mean the my ortho didn't really tighten them?

Hello. This is my second time around getting braces. I'm 28 years old now and when I first got them I was much younger. From my 1st round of braces I always took an ibuprofein before the tightening since it always used to hurt but now it didn't at all. I felt some pressure during the tightening but no pain. Why is a process that used to hurt not hurting at all. The ortho said it would take me 6 months to 1 year to get my teeth back on track as they were. Is he trying to extend my treatment?
