Can anyone please help me work it out

[Staceyaa]

I need to go for blood tests to make sure I am ovulating, she's told me the 2nd day and day 21, so do I need to book in for bloods day 2 while I am on my period? And 21 days after the day I started my period? Sorry for sounding thick but she's told me that much at the doctors I am confused lol :(

It'll be the 2nd day of your period (I thought it was normally day 3 but go with what they've told you).
The day 21 is to check for ovulation. It's normally done day 21 as they base it on a 28 day cycle. However to get the most accurate result, you should have the test 7 days before your period is due. So if you normally have a 30 day cycle for example, then book it for day 23.
Cycle days are based on when your period starts. So cycle day 1 is the first day of your period.

Thankyou for answering my question :) I have missed out on the day 2 then because i started my period Monday, so I will have to book in day 21 now and then day 2 ov my next period, I am sometimes couple days late on so I hope the results don't come back wrong because of that :(
