Yes! At my last clinic they had the same protocol and this happened to me (success/kids)

and it was my successful cycle, after two fresh failures just prior . I had a bleed just like you describe, not a heavy period, but a definite bleed beyond spotting. It lasted a couple of days and my donor was stimming already too. When I went in for u/s a few days later, everything was fine, my lining was the same as it had looked at the prior u/s, and they decided to proceed - so glad we did, b/c we had twins from that cycle .
BTW my new RE (where I went to conceive a sib) does not use lupron at all - and I had much better luck there.
Hang in there!! Hope it's a good omen for you, as it was for me. Best wishes for a successful cycle,
