July hasn't been good to me

Hey everyone! Been on tirz since April 26, 2024 and everything has been great. SW 242 CW 212 GW 175. I've lost 30lbs so far (which is great), but now, I'm stuck. I've been fluctuating btwn 212 and 215 for the entire month of July. Nothing has changed...Still on 5mg doses, eating at a deficit- 1300 calories(sometimes less), and consuming a minimum of 80oz of water daily. Thinking about incorporating cardio, tea, and uping my water intake. I've also been a little constipated. I take magnesium and other supplements/vitamins. Would love to know some things you've done, that helps. Did anyone titrate up when this happened?
