HSG (again!)

Sorry to bang on about this HSG, I'm still waiting for the results, but could I ask the ladies here who've had it done one question? What was your AF like afterwards? Af came on today but it's really light, not really spotting, but much lighter than normal. It if wasn't totally gross I could have gotten away with using just one super mini tampon all day (sorry if TMI)!!!!! Is this something anyone else has experienced?
