Currently aboard the Ark as an AFAB human passenger, you still suffered from periods. There wasn’t a negative stigma about the matter, however, given that these were cybertronians with no grasp of the concept. So floating in space, you would still bleed verbatim.

At the moment, you were lying miserably in your little diy bed.. situation. The Ark wasn’t built for humans, or human sized mechanical organisms, so you had to make do with what you brought from earth. Some blankets and a few pillows, and with help from some of the Autobots, you had fashioned a bed-box sort of thing. It was nearly like a coffin, but rather, much more comfortable and welcoming for sleep. Or suffering from a menstrual cycle.

As far as Optimus and the other autobots were concerned, you were just unwell. They still didn’t quite understand the concept of a period, but nonetheless, they tried. And Optimus being the optimal leader he was, wanted to help and understand to a tee.

He sat beside your bed-box, the expression on his faceplate relaxed and neutral. He gave a wave of a servo to greet you.

“I heard you were in pain again, explain why?” He asked with concern.
