Would it be silly to have my day21 bloods at 6dpo rather than 7? It will actually be day 21 (I ovulated day 15). There shouldn't be a huge difference in levels between the two days should there? I have 10-12 day luteal phase so it would be more on the middle of luteal phase than 7 dpo.
From a practical point of view it'd be much easier for me to do them today (I can go whenever - just need to take my form to the hospital)
