I'm home. Phew.
No more bleeding. Cervix is a "strong 2.6 cm" according to sonographer. Having contractions, which seem to be Braxton Hicks (I can't feel them, and so far I'm not going into labor). The doc upped my meds and I'm going to the OB for another check tomorrow.
More later when I figure out how to remain at 45-degree angle or less and type on the computer without my back getting very, very angry.
