At the Last Supper, Jesus said, “Take this bread. It is my body.” The he said, “Take this and drink. This is my blood. Do this in memory of me.” Catholics believe this was the First Eucharist, that through some miracle the bread and wine actually became the body and blood of Jesus Christ. Catholics reenact the Last Supper during every Mass, where the priest, acting in place of Christ, changes the bread and wine into the body and blood of Jesus Christ. This is a great sacrament of thanksgiving and unity of Catholics. Anyone who does not believe in the actual presence of Christ and is not united with the Catholic faith is asked, out of respect, not to receive the Eucharist. Catholics, out of respect for other Christian faiths, do not receive Communion in non-Catholic churches. Until you formally join the Catholic Church, please do not receive the Eucharist. If you are interested in joining or just learning more about the Catholic Church, contact your local parish and ask for information about their RCIA Inquiry group. You can go and ask any questions you want. This is the first step in RCIA (Rite of Christian Initiation of Adults) but you can stop at any time. There is no obligation to become a Catholic. Some resources: http://www.archdiocese.la/evangelization/rcia/index.php With love and prayers in Christ.

You are a Catholic, so, technically yes after you go to confession -- but there's more to it. I recommend talking to your parish priest. He will probably recommend the RCIA so you can learn what the Catholic Church teaches. After you learn it, if you accept it and go to confession, then you should receive Jesus in Holy Communion. I must tell you to get ready by praying a lot because being a faithful Catholic in today's world is nearly impossible. But if you ask for God's help, all things are possible. Have a look here beginning on page 11 for some of the teachings that many in the Catholic Church often wrongfully dissent from: http://www.dominicanidaho.org/docs/givingtestimony.pdf Based on the smattering of information in your question, I would advise you to not approach the Sacrament of the Eucharist at this present time.
