Did I stop growing? What can a teen do to grow taller?

I’m 14 years old and have been 5’6 for about a few months now and I’m not sure if I should be worried or not. I hit my first growth spurt back in 4th grade when I was 4’9 and grew, by the time I was in 6th grade I was 5’1 . Then 7th grade came and I grew 5 more inches. By the time the pandemic started I was 5’6. I started 8th grade and finished 8th grade (currently about to go to 9th) and still haven’t grown a single inch. The doctor says I have a lot of testosterone and should be exercising more so I did but no signs of growth yet. Is there a certain exercise or medication or any remedies I can take to increase my height or maximize it?
