Hi Sirenz, what you are experiencing sounds very similar to what I am going through. Someday, I get more aches and pains especially if I move a lot... other days, I feel perfectly fine. I never had any bladder straining because my bub's constantly pushing on my bladder so I have to go to the loo quite often... As for bowel movement, I had struggles with that two weeks ago. The joy of pregnancy sure brings a lot of changes in our bodies. But what you are going through is very common especially in the third trimester as there's lots of changes in our bodies preparing for the birth. Sit back and try to relax! Hope you feel better soon.
