Hi, I’m knew to this forum, I’m 31 and have been trying to conceive for a year. I appear to have 40 day cycles and my GP has told me after recent blood tests that I am not ovulating- or certainly haven’t this cycle. I’m on day 36 at the moment and I get positive opks around day 25 each month. Is day 25 too late to ovulate? My GP says it is. I suppose I’m still clinging to hope that he’s wrong which is silly really...

I think it's entirely possible that you're ovulating around day 25...this would fit in with your 40 day cycle. Have you had bloods to check for ovulation? I ovulate around day 21 (but with a lot of variability) so when they did my bloods to check for ovulation on day 21 (which is when they usually do them) it looked like I hadn't ovulate but when they did them on day 28 it confirmed I had (but I had to lie to the nurse when having my bloods done and say it was day 21 otherwise they would have refused to do my bloods!)

Thank you for your reply. Yes I had the day 2 and day 21 blood tests. It didn’t surprise me that the result came back as it did considering my cycle length. I asked the GP whether it’s possible I ovulated late and he said it is highly unlikely and he would just do the day 21 test again (but only on day 21, no later). Perhaps I need to lie and get the test done later in the cycle like you did.
It's so frustrating isn't it? Once I got to fertility clinic they assured me I just had a long & variable follicular phase (due to mild pcos) so was ovulating late in my cycle, but in my experience GPs knowledge of things fertility related is very limited! Hope you get some answers soon xx
Day 21 bloods are only meant to be used if you have a regular 28 day cycle. It's a waste of time otherwise. You get a period ~10 to 14 days post ovulation so sounds about right for your cycle length. I don't have regular cycles so have never had day 21 one bloods. I have had corpus luteal cysts on ultrasound scans which is a sign of ovulation. Ask the gp about that. May be more sensitive in your case.
