I am on the pill simply to regulate my cycle. I got my period while I was still in the hospital (about 1 week early) and it basically didn't stop until week 5 post-op! At my 2 week post-op appointment, I mentioned that I still had it and they said that it was completely normal because hormones get out of whack when we lose weight, so it's even more so after WLS. It got lighter after about 2 weeks but I definitely spotted for 5 weeks...!!!
