Almost 6 weeks, no symptoms

Hi everyone! I'll be 6 weeks on Thursday and don't have any symptoms. In fact, it seems like the symptoms I did have disappeared. Everything I've experienced so far had been very mild except around 4 weeks my breasts were killing me but now they're barely even tender. I've had no spotting or bleeding. Some days I have a decent amount of white-yellowish discharge (sorry TMI) but it doesn't smell or itch so I don't think it's an infection. I'm just nervous about MMC because my symptoms, if I can even call them real symptoms, don't seem to be intensifying. How long after a MC this early on would bleeding or cramping begin?
