Is it time

For starters I'm 14 and had my periods for 4 years already and recently I've had a lot of medication changes but none of what should mess with my cycle I have been asking when I start a new medication but this is the second time that I've gone through this It's like I will go three months get a period 3 months and then get it period And I'm not really sure what's happening is this the time that I should go see a gyno my mom is aware of whats happening and none of my health problems should mess with my cycle either and im at a standstill on what to do
