C172 student pilot reported an airborne conflict with a citation in the pattern at bdn.

Narrative:

On downwind leg and at my abeam point of runway 16. I heard a citation call to FBO he was dropping off passengers and would need a spot to park. This was the first call I heard from the citation. I called my base turn when I heard the citation announce he was on a 2 mile final. I was unaware of the citation's speed or location up to this point. I conducted a final check and could not see the citation and was already at my point to turn final within 1/2 mile approximately 500 AGL. There were two helicopters behind and to my left on downwind legs to land on taxiway bravo. I called and completed my turn to final; when I saw the citation approximately 200 feet above and 500 feet to my right. I did not feel I could make a turn back to the base with the helo traffic; luckily at this point the citation called and conducted a go-around.I either missed the call the citation was on a straight in final or he didn't make one. Either way; I had been in a left pattern conducting multiple touch and goes as the only fixed wing aircraft and didn't realize there was other traffic for runway 16. I unintentionally cut in on the citation's final due to my lack of understanding the citation location due to abnormal communication and my lack of understanding how fast the citation could cover 2 miles.
