GA student pilot reported an NMAC with a helicopter in the traffic pattern at a non-towered airport while on takeoff.

Narrative

I was practicing landings in Aircraft X [and] completed 6 with Flight Instructor and did 2 solo landings. ZZZ is an uncontrolled airport; fairly busy; and there was a lot of radio traffic. During the time I was flying left-hand patterns; there was a helicopter practicing landings in a right-hand pattern and was turning base over the numbers which made him very difficult to see. Also; I did not hear a radio call from the helicopter for his base turn or his turn to final. I don't know if the pilot didn't make the radio call or if he was covered by other radio transmissions. My instructor pilot confirmed that he did not hear the call either. Once I rotated on takeoff I heard 'he's 300 ft. above' but that was the only part of the call I heard. It's my understanding that the helicopter may - and I emphasize may; because I did not see him - aborted his landing and executed a right crosswind turn. I may have been on takeoff while the helicopter was on final and/or landing but I believe I was ahead of him as I did not see any traffic on takeoff.
