Irregular Gestational Sac

I had to go in for an ultrasound to rule out an ectopic on Tuesday. The good news is, not ectopic. The bad news was that the sac was empty (which I posted about below), though I was starting to feel ok about that because I think my levels just weren't high enough to see anything else. However, I emailed my dr to ask her for her interpretation of results (she was at her other location that) and she said she is still concerned because my sac is slightly irregular. She said it could be nothing and everything could develop fine, but it can also be a sign of a problem. Combined with my low progesterone levels and light spotting she finds it to be cause for concern. I have a followup ultrasound in the morning (I haven't spotted in 2 days, so I'm trying to remain hopeful!). Has anyone experienced this? I'd like to hear outcomes either way.
