Long story short - when you've to try and have a blood test as soon as your period starts, what cycle day do they want you on? I'm stuck with going on day 4 at the earliest because of the weekend, and worried that's too late.
The longer version if it matters -
I've got PCOS and receiving treatment at my local NHS fertility clinic. I was told to book in for one last blood test when my next period came, and then start letrozole the period after that if the result of the bloods is fine. I've waited blooming 86 days for this period to come so I can get the test done and sods law, it started at 6pm last night (Friday). I obviously now can't even begin booking the blood test til the clinic reopens on Monday, which will be cycle day 4 by then. Is that too late in the cycle for this type of test? I feel like cycle day 2 or 3 rings a bell for the ideal test date. I'll be so disappointed if I miss the cut off after all this waiting :(
