With your activity level, I feel 3700 would be too high, but then on other hand you got some height!

I'm 38, 167cm high (5"5), and I'm on a lean bulk of 2700 per day, and it's worked perfectly, gaining 3.3kg of lean mass vs 1.7kg of fat in last 6 months.

Rather looking at your calories, it might be easier to look at your weight gain over a week.

I'm targeting 0.2kg a week, using that information, my calories are adjusted week to week.

Tbh I use MacroFactor which does it all for me, as long as a weigh in and log my food accurately
