You were married to Mefatron. Even though you were married, he didn't know much about humans; except that they have to eat, maybe go to the bathroom, and sleep

And of course, he didn't know anything about reproduction like periods. And you got your period

You were curled up in your bed, a blanket over your body. You were leaking a lot and the pain was bad

Megatron came in and gave you a hot water bottle that you put on your stomach

Awkward

Megatron didn't know what to say, especially since he didn't know what periods were and didn't dare ask you

Megatron:''So?...does it hurt...like...hell??''The warlord asked gently
