TMI - baby dropping? 33w2d

Claire

So this is pretty gross but I'm 33w2d and this morning I had a pretty painful bowel movement (felt constipated then had diarrhea, with sort of hemorrhoidy veins partly sticking out afterward - sorry, gross, I know) but now all of a sudden I feel like my lungs have TONS of space - breathing feels way easier than it has for weeks, and I feel like the pressure has shifted lower into my pelvis (so squashing my bladder and lower intestines but definitely less pressure on stomach and lungs).

From what I've read this sounds like the baby dropping, but I was wondering if anyone else has felt something similar, since it seems like 33 weeks is a little early. SO doesn't see any difference in belly shape compared to yesterday, so maybe I just really needed to go to the bathroom ;)

Okay, end of TMI.
