Progesterone levels blood test day 21

[greatbiggiraffe]

I have been ttc second child for coming up to 1 year (I am 37). I have had blood tests to check hormones levels ( taken on day 2 of cycle and should have been day 21 of cycle but was day 24). All levels were within ranges apart from progesterone on day 24 which was 25 and levels should ideally be over 30. Would this be causing issues in ttc and is there any supplement I could take to try and increase my levels? Or could it be that the blood test was taken too late to be useful? My cycles tend to be around 30 days but with the odd one that's around 34/35. Thank you.

It was probably just taken on the wrong day. A level over 30 confirms you released an egg 7 days before. If you don't ovulate, there is almost no progesterone present.

If I were you, I'd use opks next cycle and ask for a repeat of the day 21 bloods.

Thank you I feel relieved to hear that and I will ask for a repeat of the blood test on the correct day.

The important thing is not what day of the cycle the test is done but how many days before the start of the next cycle. I think 7 days before the period is ideal, hence it's called a day 21 test because the average cycle is 28 days. Your result needs to be interpreted in that light. Either way you'll need to test again next cycle. Opks can help pinpoint the timing and some surgeries will test you twice in a month.
