Hi MMM - I had those aches a couple of days ago. I think it's just round ligament pain and the uterus stretching. It's not quite crampy... just a tight achy feeling. I know it's hard not to worry, but no cramping and no bleeding is a good sign. I think our bodies are just stretching and getting everything ready so our little ones can snuggle in there for 30ish more weeks!
