Cramps but no spotting yet - is it happening soon?

Doctor saw no heartbeat at our prenatal appointment on Tuesday. About 9 weeks. Today I started feeling period like cramps - nothing too bad, but I don't normally get much cramping so it's noticeable. No spotting yet. I'm just trying to figure out what to expect timing wise - is my body close to pushing it out? The anxiety of waiting around for this is killing me and I think I'm gonna go pill route, but maybe my body is taking care of it itself? I just don't know what to expect, and on top of that we're supposed to attend a wedding on Saturday (TBD if I'm up for that). Was reading some experiences on this subreddit and it seems to be all over the place in terms of timing....
