LH surge & ovulating without mature follicle

[Tinkerbell3]

I'm currently going through a natural FET, had a scan yesterday (CD13) was told my biggest follicle was only 12mm but today I've had a temp rise (although have a bad throat ATM so not sure if that might of affected it) it had dropped yesterday so looks just like usual OV pattern and today I've had a +ive OPK. Could I ovulate without having grown a mature follicle? Perhaps would explain why I'm not falling pregnant if this is happening month after month.
Plus if I've ovulated (going by temp spike) wouldn't I have had the positive opk yesterday and not today?
The one cycle I needed everything to go as usual it's all messed up!

Yes, usually you will have a temp rise the day after ovulation, which is 12-36 hours after your +OPK. Do you have PCOS? Some women with PCOS get false positive OPKs because they have a higher LH levels.

Nope, no PCOS and infact for the last 3 years since we've been trying I've had regular 29/30 day cycles with ovulation happening cd15/16.
I started temping soon after we started trying and 9 times out of 10 I have a dip on day I ovulate then as you'd expect a rise, only now and then I don't have the dip first and yesterday I got the dip, today rise but it's the +ve opk this morning that's throwing me.
I figured they just might not have actually spotted a larger follicle but it could have been there, my lining was 9.6mm so def thick enough for ovulation to be close.

I have another scan and a blood test tomorrow so we'll see

Hi! Just curious to see what you found out, as I am having the same issue. I got a positive OPK today but yesterday I didn't have any large follicles at all... I do have PCOS though, so I guess I could have a false positive as Lemonade said...

Hi, I have the problem with positive opk without o taking place . I think that is our main reason for not getting pregnant.

Turned out the +ve OPK wasn't so positive (don't think I'd use Superdrug ones anymore) my temps dropped after 3 days and I finally ovulated a few days after.

I'd only ever used the internet cheapies before and always got negatives even though I was ovulating, typical really

It is better negative with O than positive without (this is my case) .
