Hi Cassie - the tinnitus could get worse on the Utro as prog can negate the positive effects of estrogen.
I'm highly prog intolerant and get all kinds of side effects on prog - it's as if there's no estrogen circulating, it's stripped out or negated by the prog.
When I was first plunged into meno, tinnitus drove me mad at night, due to the sudden drop in hormone levels.
Yeah, what next, it never ends, this flipping meno.
