I did. Mine returned straigh away, in fact it was so close after giving birth I wasn't sure if it was still post parturition bleeding or my period. And I even went to the dr about it because it was so heavy. I had a couple of hours where I honestly thought I was going to bleed to death it was just pouring out of me.

Spock is now 19months and it was been regular (30ish days) since, and deffinently heavier compared to before giving birth. Not as crazy as the first one, but still heavy.
