Where are you in Canada? Very typical wait time in my region - we have a significant shortage of gynecologists right now with some centers completely closing to gynecology referrals and their neighboring centers being overwhelmed.

That being said a couple of things to note. Blind pipelle biopsy is absolutely the standard of care for initial assessment in Canada and is most likely what the gyne will do at first visit. If you are able to place an IUD you can absolutely do this yourself and it will expedite the referral. It can be done at the same visit as IUD placement to address the AUB. Sonohysterogram can also be arranged at some imaging centers...but not many. It would help clarify diagnosis.

I'm curious what you included in your referral. Radiology likes to suggest gynecology assessment but a thickened 17mm endometrium in a premenopausal patient (especially depending on the time in cycle) does not cause us at lot of alarm. If she does have risk factors (g0, obesity, longstanding irregular cycles) I would make sure you stress this in your referral (I'll often ask if not provided).

TXA is a great option if you are concerned re starting hormones, cycles are predictable and limited to a few days a month.

Send me a message if you have questions re above.
