Forgotten Sins

[Justin Alphonsus]

On a related note, I have come out of confession and then remembered a sin (in doubt as to whether it is mortal or not).  Since I was then at mass, I didn't know if I should go forward to receive Holy Communion.  So, if we just went to confession and confessed all the sins we remembered, but then remember one we forgot, should we refrain from receiving Holy Communion or just not worry about it and mention it in the next confession.
