Muscles still fatigued after almost a week of rest

Hi everyone! New here because I came looking for an answer to this and couldn’t really find it. I’ve been training (mostly body weight, some light weights) for the past 6 months. I’ve taken forced breaks every two months or so due to injury or illness. I finally got to a point where neither of those things are creeping up on me, but I felt really achy all over and tired so I decided to take a rest week.

I’m at the end of the week and I’ve done: stretching every day (part of my normal routine), foam rolling, walking, and yin yoga. I just can’t seem to shake the kind of achy joints and my muscles feel REALLY tired at the end of every day. There’s no pain, it’s not an injury thing, I just don’t feel good enough to get back on the horse yet.

Did I just overtrain? I basically started from zero after being bedridden for an entire pregnancy. I’ve been athletic my whole life and I’m not used to this lol.

Any and all pointers are welcome! I won’t go back to my regular workouts until I’m feeling better, but anything I can do to help it along would be great. Thanks!
