PCos and thick lining after Provera - is 8.5mm normal?

Hi everyone,

I’ve had irregular periods since I first started having them and was diagnosed with PCOS a few years ago. I recently went to a fertility clinic to talk about my irregular bleeding and lack of ovulation.

I hadn’t had a bleed for around four months (my last one was Provera induced). When they scanned me before starting a new course of Provera, my endometrial lining measured 7mm. The doctor prescribed Provera for 10 days (5mg twice daily) and told me to come back on day 3 of the next bleed to check if my lining had thinned. If it hadn’t, they said they would do a biopsy.

I went back while I was still bleeding, around day 4, and the lining measured 8.5mm. A different nurse did the scan and said it looked “smooth” with no clots or obvious abnormalities, so no biopsy was done at the time.

They’ve said they might rescan me a few days after the bleeding stops, about five days later, to see if the lining has gone down.

I’m confused and a bit anxious. Is it normal for the lining to still be 8mm while bleeding? Could that just be blood or tissue still being shed rather than new growth? Or is 8mm at this stage usually a sign of hyperplasia?

I’d really appreciate hearing from anyone who’s had something similar, especially anyone with PCOS who’s had thick linings after a Provera bleed.don’t know if that’s just my normal as I haven’t been scanned straight after a period for years and back then Inwas a lot slimmer and periods kind of regular. Thanks!
