I've experienced some of these signs during the early onset of hypomania. Sometimes doctors look for how distressing these symptoms are to you when making a diagnosis or how harmful or detrimental are these signs when it comes to your functioning and sense of wellbeing. Lack of sleep is a big sign to me that hypomania is starting, noises are more intense, increased sexual thoughts and risky behaviors, the shopping, jumping from idea to idea, and other signs and symptoms.

It could possibly be hypomania when I compare it to my experience, although a doctor would likely want to rule out other possible causes. Only a doctor could make that determination. This is absolutely worth exploring more with your pdoc for proper treatment.
