Lh peak suddenly gone from day 13 to day 10, spiralling. Dor and rpl

Hi, I have DOR, I'm 37 and had 3 miscarriages this year. Due to start IVF next year. I always always always have my lh peak on day 13 of my cycle so presume I ovulate day 13 or 14. I had a scan last month and follicle on day 13 was 24 mm.

This cycle , I decided to test early as my RHR had been rising (it's been flat for last 2 cycles post miscarriage) and I had a positive ovulation test this morning cycle day 10, a very dark line for me.

I'm super worried as we only have 2 cycles left to ttc before IVF and now feel like I'm out this cycle. I felt safe with ovulation being due next week that I definatley wouldn't be having a miscarriage at Christmas. Now I'm worried about that too (could be chemical). I'm due a hysteroscopy in Jan and the date was perfect in my cycle to be able to TTC still. Now it's going to be on ovulation if I ovulate day 14, or after if I ovulate day 10, so that's that cycle out too ☹️

The only difference is I took progesterone from 3 dpo to 12 dpo last cycle and got my period one day later than I normally would. I also had my first acnepuncture on day 6 (4 days ago) and felt a lot of movement in my belly during this, lots of bubbling and movement feelings.

Has anyone else had this after acnepuncture/ progesterone? Or is this likely my fertility falling off a cliff just before I start IVF?

Thanks
