So I highlighted the important parts here. Some of it is contradictory.
If you did as much research as you could, you would NOT NOT NOT have done tren in your first cycle. You also would already be well versed in what PCT looks like, and why taking 4 weeks off between cycles is just daft, UNLESS you are already on TRT, your "cycles" are actually blasts, AND blood work says that you are good to blast again in 4 weeks.
But, you are in the right place to learn now.
Read the link that AG posted, it will answer all your questions. It will also highlight how little you know now, but we all start somewhere, so take this as a learning lesson and move on.
