17yo, 5'10, 68kg (150lb)

Started off completely skinnyfat, gained muscle December-April, have been cutting since then. I have been plateauing for four weeks (marginal strength gains) and am seriously struggling to lose the remaining fat on my stomach.

Would it be a seriously bad idea to start a slow bulk again? I want to prevent more muscle loss but don't want to continue having a stomach like that.

Thanks trp
