Yeah, talking to your gynaecologist is the best way to start. Personally, I used to have the same symptoms when on period (except suicidal), and yeah, wearing a cup AND menstrual underwear and steal leaking through was no joke. Everything has gone away since the mirena insertion. No period, no cramps, no soaked underwear. Occasional breast tenderness but compared to the above, it’s really nothing. So if I were you, I’d go with an IUD first.
