My suggestion is that you are at the point where you should shift to reductions if under 70. This looks a lot like SRT effect. I know it’s only the third cycle at this dose, but there were times post SRT when I did back to back reductions even sooner.
Listen to your gut. I got a feel for when Neko was telling me she needed less juice. MC snacks may be one clue. Let’s just say I got a feeling on the larger reduction last time. Going all “Kermit coloured” can be a sign. Much easier to go back up if need than fight lows.
