Holy Eucharist

[Maccabeus]

How long is it Ok for a a person to receive the Holy Communion before he has to go to Confession again?
My problem is that I got married few months ago, and I haven't been to Confession for many years, Before the marriage I tried but ran out of time, & wasn't able to do it, went around the city looking for a church that I could confess in. Its really bothering me that I didn't do it, Before the actually wedding minutes before I was to walk out to meet my Bride, I confessed everything to the painting of Divine Mercy that was
inside the church's side room. It all came out of me like pouring wine out of a jug. During the mass I accepted the Holy Eucharist/ Wine.
Bottom line is I felt horrible about it.

When we are sure we have committed a mortal sin we are excluded from the reception of Holy Communion, however the Catechism of the Catholic Church teaches:

1452 When it arises from a love by which God is loved above all else, contrition is called "perfect" (contrition of charity). Such contrition remits venial sins; [b]it also obtains forgiveness of mortal sins if it includes the firm resolution to have recourse to sacramental confession as soon as possible[/b]

So you must now confess any mortal sin which you remember before receiving Holy Communion again.
