Increasing pitch angle is not the first stage of a go around procedure.
First you increase power as you are already low and slow
Then you apply some elevator pressure to slow and stop the descent
once stabilised you can think about climbing and starting to retract flaps at appropriate speed and retracting undercarriage
climb to go around altitude, enter the pattern, or whatever else ATC tells you to do.
In a nutshell power, pitch, flaps, gear.
