blood tests & ovulation?

Post by bectonks » Mon Oct 21, 2013 12:38 pm

Just wondering can a blood test determine when you ovulate in your cycle & does it matter where in your cycle you have it done?

From memory you have it down post o say day 17 of a 'regular' cycle and it picks up hormon levels. Your dr should be able to explain it tho when it's ordered.

Lady J is 7 months, self weaned from a shield at 5months and now feeding like a pro.

I had it done pre kids to find out why it was taking so long for us to conceive. I can't remember exactly the dates, but I think it was about day 17. I know the doctor moved it back a day because my cycle was a bit longer (31 ish days). It showed I wasn't ovulating because the hormone wasn't present. I went on pills to make me ovulate, had another blood test and confirmed ovulation had occurred the next cycle.

As an aside, the tablet were awful. One side affect is hot flushes and it was really horrible. I'm sure not looking forward to menopause!

I have always had blood tests at cd21 of a 28 day cycle to determine ovulation. So 7 days after you have ovulated. The level of progesterone will tell you if you have ovulated.
