Clearblue fertility monitor no peak???

[Lisatay25]

I'm using the new clearblue monitor for the 1st month I'm on cd 25 a d still not peak but monitor is still showing high ?? Anyone else had this ?? Xx

Are your cycles normally regular / 28-35 days ish?

I never had a peak either and had very long cycles. It turned out I had PCOS and didn't ovulate.

I didn't get a peak the cycle I got pregnant when I clearly did ovulate! The machine is less clever than it makes out. It looks for oestrogen and gives you 'high' as soon as it detects it, then it looks for the LH surge to give you 'peak'. If it misses the LH surge it will keep saying high until you have used all 20 sticks, it is no longer measuring oestrogen and will not respond to the drop after ovulation. If it keeps happening it might help to change your testing time slot. The LH peak is short lived, if it happens in the evening and you test in the morning you can miss it.
Do you think you ovulated from other signs ? (temping or EWCM)

Also, some people don't get a peak every cycle - just means you won't have ovulated. Perhaps start tracking your temps (if you don't already) or, better still, ask your GP for a 'Day 21' (would need to be a little later if your cycles are longer than 28 days) blood test.

What are the 'day 21' blood tests all about?

Hi I am using my monitor and on day 8 of highs here and first cycle. Used it for dc1 and did get peaks but not first month so I am going to use mine for another 2 cycles and hopefully it will work.

I'm not sure cuz don't really do temping gonna start doing that this month I think I had ov cramps 3 days ago but I don't know if its my mind playing tricks it's my last test stick tomoz so fingers crossed I have ov :) xxx

The CBFM's are not as clever as the manufacturers like to make out! I wouldn't rely on them alone, it is best to be recording other symptoms such as EWCM too. I used a CBFM for 4 months and it only identified ovulation once, despite the fact that I was also having blood tests to confirm ovulation had had happened!

The Day 21 blood tests are misleadingly named. Basically they are blood tests taken 7 days after you have ovulated to check progesterone levels. You only have them on Day 21 if you have a regular 28 day cycle. When you ovulate, progesterone levels rise for 7 days before falling again, the aim of the blood test is to try and catch the peak level.

It is worth noting that your GP probably won't send your for such a blood test until you've been TTC for at least a year,or are having irregular periods.

I don't know if this is right but I'm sure I read somewhere that CBFM has to learn your cycle and basically records you as high all the time for the first ,month and then adjusts to your body and starts recording peaks. That might explain why it is problematic the first month or when you're only starting to use it again after a bit.

May have got that idea fom th Amazon reviews, as I am thinking of buying this and read them! Or there was a thread on here recently.

Frankel is wrong about the Day 21 tests: I was given my first in my third month of ttc (last month). I was worried as I had a mc in my first month of ttc and no success since, so it was easy enough to book in for. This month (my fourth of ttc) I am having three 'Day 21' tests: on days 21, 23, and 26 to try and make sure we catch the progesterone surge if it happens. If you're concerned, ask for it. I'm only 24, so it's no age-dependent either.

I can only go by my own experiences. My GP told me it was NHS policy that you had to be TTC for 1 year before they will start investigations (6 months if you are over 35). I had my first test done after 8 months because my periods were very irregular.

That's interesting, Frankel. It's obviously not difficult or expensive for them to do as my GP was happy to do it just to keep me happy, and the results were back less than 48 hours later. Another GP at my surgery has said that they wouldn't look at Clomid or IVF or anything until you'd be ttc for a year, but in terms of Day 21 tests, it's fine. I think it's a useful thing to have.

Hi I had all highs the first month using the the CBFM and then had a peak in the second month which resulted in a bfp, currently 30 weeks pregnant now (and 42years old). I think the first month it just gets to know your body.

That is encouraging as all highs here now- and congrats!

The monitor doesn't necessarily just give you highs the first month, but it can happen. You can read the sticks yourself if you want. If you see the LH line being stronger one day, and then it goes down again, the monitor might have missed ov.

Thats brillant news ,Im 41 and going for tests next week as been trying for a year and i got pcos, I brought this machine last month.
