Some people say that there is a pre-trib rapture ... and they are correct in a sense.
Some people say that the rapture is after tribulation ... and they are right in a sense, too.
Others say that the rapture happens at some point mid-way during the tribulation ... and they are correct to some degree.
In truth, we are already in the "Day of the Lord" and have been so for over one year. There are ten years in the "Day" ... seven of which are called the "Great Tribulation." Revelation chapter 2 verse 10 makes it clear that there is ten days of tribulation. We endure 2 more years of tribulation as the birth pains increase and then (after the first harvest) the Day turns terrible, so that all things can be fulfilled.
Here is the sequence as I understand it.
* The Day of the Lord begins (10 years long of tribulation)
* Birth pains intensify (CURRENT PHASE)
* Rapture occurs - the first harvest
* Great Tribulation begins (the second harvest is gleaned throughout the seven years)
* Worldwide panic from rapture / the antichrist seizes worldwide control
* Israel gets a peace agreement that lasts 3.5 years then broken even though it was promised to last 7 years
* Armageddon
* Judgment
* World is cleaned up (rebuilt) by the Lord
* The Day of the Lord ends and the Millennial Reign begins (1000 years)
* After 1000 years ... the mystery of the Eternal state is revealed as New Jerusalem
Please everyone study Revelation Chapters 20 & 21 for better understanding of Trent's last 2 events listed above.

Servants, stand up! says the Lord of Hosts. Stand up for Me, and I, even I, shall feed you with knowledge and understanding...the Word of God as your drink, and the knowledge of the Lord as your meat...you shall sing and you shall stand up, you shall shout with a new voice in the face of adversity. And in that very same day, you shall be gone, you shall surely be taken and be found no more in the earth...eternal joy and all tears wiped away in the presence of the Lord, your Redeemer, is your reward, and it shall never again depart from you, says the Lord. [Jesus speaking] (Servants, in Christ, Stand Up and Blow the Trumpet! - Letters from God and His Christ - Volume 6)
