Does getting your period have an effect on your numbers?

Sorry I’m so annoying with questions. I’m recently diagnosed and just trying to survive right now. Anyway. I woke up with my period this morning and I’m spiking up above 30Mmol for literally no reason. I’ve only eaten breakfast and I calculated the carb-insulin ratio exactly the same as I have for this exact same breakfast everyday last week. I haven’t spiked like this from it before. I’m just confused. I also gave a correction dose and I’m not coming down in the same time frame I’ve gotten used to. Just curious if any other humans have noticed their period has an effect on their diabetes?

Thank you and sorry again for being a question whore. I’m very very thankful from the bottom of my heart for all the support you’ve given.
