Letrozole and v early ovulation

Hello!
I’m CD6 and I’ve just taken my last Letrozole tablet for this cycle. It’s my first time taking Letrozole, so far it’s caused my period to be very short and light, I finished my period CD4.

Anyway, to the point, I’ve just taken an LH test and it’s 0.48 on pre mom, I’ve never ovulated before so I’m wondering if this is normal the be so high this early in my cycle or if it means I’m going to ovulate very early?

Hi! I'm also currently on Letrozole, on my second cycle now. I found that 0.4/0.5 seems to be my baseline on it as I got around that result every day from days 7-12, and then when I got a positive on day of ovulation (CD13) it jumped to 1.7.

I think due to the stimulation the Letrozole provides it must make LH levels higher, even when on a baseline/mid cycle? Test again tomorrow same time and see if it's similar x

Not sure if this is helpful or not as I know it is different for everyone…
But I had letrozole as I never ovulated on my own, and I found I would have a peak shortly after I finished taking them but not ovulate, then I would peak and ovulate much later around cycle day 22-24.
I also had really light periods on them, but I didn’t haven’t any all without so not sure if it was normal or not!

Good luck! 🤞🏼

@Hannahx1992thank you for replying! I’ve seen a few people say that! Did Letrozole work for you? Xx

Unfortunately it didn’t.
I had 5 rounds and did manage to ovulate 3 times though which was a start! i think my body just really didn’t know what to do! X
