Period came early on BC help!!!

Amanda

Proof came three days early, have been on the pill for nearly 15 years, and this only happened once when I had an ectopic pregnancy -I was drinking detox teas effectively sitting out my bc without realizing. I have been on top of everything since then and nothing has changed. I did lose a few pounds due starting Wegovy (semiglutide) 3 weeks ago. Is this normal?
