My period timeline changed after my first dose of T. Basically every month it moved up a week until the third month when it went away entirely. Each time it was lighter and shorter than the last.
Had it stopped completely prior to this? At under 6 months on T, it's pretty normal to experience some fluctuations in terms of your period. Unless it is a lot of blood or going a week without stopping, I wouldn't be too concerned. I would keep notes about when it started/stopped and how you would describe it (heavy, light, spotting, etc.). With the increase to your dose, it's possible that your body is finally shutting your period down, and is getting out whatever is currently in there.
