Jasminstar - I discovered a possible thin uterus lining at my first ultrasound after starting to see FS. On that occasion, it was CD17 and my lining was only 3mm. I had just finished a round of Clomiphene tablets, and my FS said that it was likely the tablets that made my lining so thin. I was a bit more skeptical though, because I also thought about the possibility that maybe my body was just like that (or maybe it was a combination of the two). I have only ever had an 8mm lining ONCE and that was on IVF, so with the FSH, my lining can get up there, but naturally (like with a FET), I don't think I'm as lucky. So I'm hoping the Progynova will help with that.

Regards your question though, every ultrasound I've ever had, they've always checked the thickness of my lining. I don't know if that gets done at every clinic, but it certainly does at mine. They check follicle development and thickness of uterus lining every time.

I've not been so lucky with the OPK's though. I got a positive result this morning (damn it), which is CD14. That probably doesn't sound unusual to a lot of people, but I really thought I'd finally figured out my body, and that I wouldn't ovulate until maybe CD17-CD19. So I rushed into my clinic this morning for a blood test, because I really wanted to get the results of my hormone levels today (if in fact I'm going to ovulate today or tomorrow). I would like to have the results for future reference. I haven't got the results yet, but they might not call til tomorrow cos they were pretty busy at the clinic today. My biggest concern now is the thickness of my lining. I still have an ultrasound on Monday morning, so I'll be very interested to find out how thick the lining is then. I hope I'll at least be at 7mm, but only time will tell I guess.

Has anyone got any idea to what degree your lining thickens over time? I ready somewhere that it thickens approx 1-2mm every second day. And that doctors like to see 8mm around ovulation.

Loops - good luck for transfer tomorrow. Hope everything goes well for you.

Williamsemma - welcome to BB and good luck with your cycle.

Emerald star - thinking of you and your upcoming BT. Fingers crossed. Hope you're doing ok.

Juniper - thanks for the update on your LH levels for a previous IUI. I checked back on my own BT results, and I also came across one cycle where my LH was 45 and I was just about to ovulate. Although i had other cycles where just before ovulation, my LH was under 10. I just can't pick it with my body. It is a complete mystery to me.

Bubbless - Welcome. Good luck for EPU on Monday. Fingers crossed for you.

Sorry if I missed anyone.

Wishes xoxo
