Hello, lovelies!

I'm now at around 3 months of not having a period. While I don't always have the most regular periods, they are usually pretty bad (heavy bleeding, severe pain, etc. To the point where it's suspected that I have endo, but they haven't wanted to invasively check for a diagnosis).

I've had some things that, with missed periods, made me wonder whether I could be pregnant, like sore breasts, fatigue, moodiness, (some urinary concerns that turned out to be an uncomplicated UTI) changes in apetite, etc. However, I haven't been throwing up or anything like that.

I've taken urine pregnancy tests 3 times over the last month and a half, each was negative.

Has this ever happened to you? Any thoughts on what could cause multiple missed periods since I'm not pregnant? Is this something serious enough to see a doctor about?
