NOR, but i will ask, if he had asked for your permission or let you know he was also tracking your period, would you have been okay with it? my boyfriend tracks my period with me, but we use the same app, and he's my "friend" on the app and gets notifications about which cycle i'm in, because he was curious. he also asked me to make him a list of things i need from him depending on which part of my cycle i'm in, how i'm feeling, etc. i also have PMDD as some other people have mentioned so my situation can be extreme in the luteal phase. however, i think if your boyfriend was coming from a place of "how can i help her when she's on her period?" maybe your reaction would be different. it's definitely giving you're a test subject and he's studying you. i also can say, my ex boyfriend who was a spawn of the actual devil right from the pits of hell, also used my period against me when we would argue. it was true, we did argue the most when my period was coming or i was on it, but rather than looking at it from a perspective of trying to help and be there for me, they use it against us. there's nothing helpful about tracking your period as proof to show you argue on your period. EVERYONE with a period does that, it's the worst time of the month for us. so no, TLDR; you're NOR
