As the title says, it’s 20 days late. I’ve taken three pregnancy tests at late days 6,8, and 14. All of them came up negative. And I’ve been on birth control for 1.5 years with no side effects and haven’t been late on a pill since November. I don’t feel any cramps or other period symptoms. I’ve gotten more migraine with aura than I usually do recently, and that’s the only weird thing I can think of. I don’t take any medication except for excedrin for migraines when I have one. I haven’t lost or gained any weight, I’m eating the same as I usually do, I haven’t changed my amount of exercise, and I don’t think I’m too stressed. I work full time, sometimes overtime, at a pizza place, maybe stressed sometimes. I have no idea why my period is so late. This is not usual for me.
