Hmmm. I think PCOS can cause bleeding, but more common to cause infrequent periods or no periods. I’m very surprised nothing can be done, and still think it might be worth pressing for a 2nd opinion - firstly to check it’s nothing more sinister, but secondly to confirm there’s nothing to make life easier for you.
I certainly thought it was bad enough having a period every three weeks, without having it all the time. And I agree it must be a horrific expense. Not the first time I’ve asked somebody this today, but is there no other doctor at the same practice you can see? Sometimes just seeing a different person can bring a whole new approach. You don’t have to switch permanently, and I don’t believe you even have to give a reason. If there are several doctors where you’re registered, you can ask to see whichever you like.
I try to keep seeing the same one, because she knows me quite well by know, and I’ve been quite happy with her. She’s not very confident about treating MS symptoms, but OK apart from that, and it’s easier than explaining everything to someone new each time.
But if I ever thought I was a bit stuck in a rut with her, and wanted a second opinion, I wouldn’t hesitate to see one of the others. Of course, it helps that she’s only part-time anyway, so it would be easier to do it without being conspicuous. If they said: “Oh, she’s not in 'til whenever”, I’d be able to say: “OK, any of the others then”, and it would just look as if I was keen to be seen, and not deliberately avoiding her.
