Is 340 an ok oestradiol reading for 4DPO? I‘ve been having night sweats so am being investigated for perimenopause although I’m only 35. I‘ve had a look at the ranges and it says it’s within the normal range for the luteal phase, but it does look like it’s on the lower end of the range as it can go up to over 800. Grateful for any insights, I’m hoping it doesn’t indicate my estrogen is dropping off already :(
