It’s also not an exact science, especially if you’re not on hormonal birth control. My cycle is 27-29 days, unless I’m stressed, in which case it can be up to 40 days. My period then lasts 3-4 days, but every 7-8 months, it instead lasts a full week and is way, way heavier and more painful than normal. No medical issues that my doctor can tell, sometimes it just be like that. So I will know that I should be getting my period in the next couple of days, but it’s never exact.
I used to be better about tracking it, but I realized I could feel a twinge about 20 minutes before the bleeding starts. Now I’ll even wake up to it, so there’s really not a downside to not tracking my period. (Except unforeseen medical issues, bc failures, and general bodily awareness)
I’m an anti-Zionist because I don’t think Britain had the right to carve up Mandatory Palestine. I don’t think Israel should have been created, but I also think nobody has the right to get rid of them now. There might come a point when the Israeli government is as unsalvageable as the third reich, but just as there’s now Germany where that had been, I don’t think the solution is to just remove the people who are citizens of Israel. I do wish the world were better at enforcing consequences on countries/leaders for bad actions though.
