When is my 21st day for the blood test??

[emmiegirl]

Hi,

I am so confused! I can have a 21 day blood test this cycle but I can't work out when I should have it.

According to my CBFM I ovulate 7 days before my period.

Am I supposed to have the test when I ovulate, or 7 days AFTER ovulation, which is when my period will arrive?

Because my cycle varies between 30 - 35 days, the Dr did mention a 23 day blood test, so I have't got a clue when to book.

Thanks!

Hi emmiegirl

You shoud take off 7 days from your shortest cycle. So you should go for your test in day 23.
Good luck

You need to go in on day 23 or a day or two earlier if the day 23 falls on a weekend.

Would not be using the CBFM - these can be wrong.

Ahh, so thats why a 23 day test was mentioned...
