Lh Surge And Ovulation Chart

Sandy asks…

Peak on Clearblue but bbt chart not corresponding?

I got a peak reading on my clearblue monitor on CD18 and 19 however my bbt has not yet increased.Has that ever happ to anyone?Also the other fertility signs like CM has become sticky and CP has also become medium,so i knw that im not fertile anymore….but i dont knw why my bbt is not corresponding to the other signs…Also im on Clomid for the 1st time from CD 5-9.

Pregnancy Advisor’s answers:

The PEAK reading on your Clearblue fertility monitor means that it has detected the LH surge in your urine. The LH surge is the luteneising hormone you get just before you ovulate. It means you will ovulate around 24-36 hours later from the first positive LH surge. Your temperature won’t rise until AFTER you’ve ovulated, so that’s why your BBT chart isn’t corresponding with the CBFM’s Peak days. The Peak days don’t mean you’ve ovulated – they are giving you warning that you will do so in about 24-36 hours.

Ovulation will only be confirmed by BBT once you’ve had over 3 days of consecutively higher temps. The ovulation day is normally the lower one. You may well find that after CD20 your temps will rise.

I don’t know if you are charting your BBT on the Fertility Friend website, but it is very good in telling you when you ovulated.

Sandra asks…

if you are already pregnant and its to early to get a positive result yet ?

is its possible that the ferlity testing strips will not work………..because each time I test with the fertlity tests it comes back negative ? Please help
ovulation tests?

Pregnancy Advisor’s answers:

It’s possible, but I doubt that’s the issue. Most ovulation tests will turn positive if you’re pregnant.

You may not be ovulating at all or you’re missing your LH surge. It’s easy to miss. Around the time you think you will be ovulating, take 2 ovulation stripes per day.

Also chart bbt and look for ewcm to indicate/pinpoint ovulation.

Good luck!

Sharon asks…


does it ever show you a smiley face on a certain day when you are actually not ovulating on that day? is it possible?

Pregnancy Advisor’s answers:

I use CBE digital and have always gotten the smiley face when I ovulate. I also do BBT temp charting and the day after I get my smiley face I’ve always seen a rise in my temps, which is what indicates that ovulation happened.

The OPK can tell you that your body is getting ready to ovulate by detecting your LH surge, but it can’t absoultely prove that you DID ovulate. Only that your body got ready to.

Is there a reason you’re thinking you didn’t ovulate? You might want to consider BBT charting which is the only definitive way to prove you did ovulate by your temp rise.

Much dust to ya

Mary asks…

After you get a positive OPK, then you test again and get a lighter/negative one, is that a sign you ovulated?

I am temping etc. I guess what I am asking is should I continue to test, or if I was going to ovulate I likely did….

in other words once you ovulate, does the OPK go lighter again? I think that is best way to phrase what i am asking. Hope this makes sense.

Pregnancy Advisor’s answers:

A positive OPK means your LH is surging, and you should ovulate within 12-48 hours. The fact that the surge is going down means your should be ovulating right now.

Here’s a chart that clearly shows hormone changes in relation to ovulation, and when LH does come down in relation to ovulation.


If your temp shoots up tomorrow, then no need to take another ovulation test, if it doesnt, then it might be good to keep on taking them until you get a temp shift with charting.

Good luck!

Carol asks…

With PCOS what steps of fertility treatment do you take?

I am currently seeing Dr. Seth Katz with Reach Fertility Clinic. I have had an HSG Test, and I have also tried Clomid Estradiol and Prochieve. Please let me know what else they can do for me? I am currently overweight and i have been working to correct this problem even though it has not happened yet.. I currently take 2000 mg of metformin a day..

Pregnancy Advisor’s answers:

Here is what I’ve found while dealing with PCOS and TTC, some of it may apply to you, some may not, just my observations/findings:

1) Chart. You need to know if you’re ovulating. With PCOS you can get the LH surge (ie test positive on an ovulation predictor strip), but not ovulate. The best way to determine if you ovulated is your basal body temperature. If it goes up and stays up you O’d (not the fun kind, but the important kind).

2) Insulin is the devil. Especially for you, because PCOS and Insulin Resistance are twin sisters and they hate you. If your insulin resistance is fair to normal, you can control it with diet. Lower carb, no sugar/flour, lots of fruits and veggies. Good book to check out is Fertility Foods by Jeremy Groll. Designed for PCOS.

3) If your insulin resistance is pretty bad and diet isn’t doing the trick, you may need some drugs to help out Metformin/Glucophage is a big helper. If that doesn’t do the trick Actos can be brought to the party.

4) Did I mention charting? You really need to know if you’re ovulating or not. Because if not, you may need some ovarian stimulation ala Clomid/Femara. It’s dirt cheap as these things go and is pretty effective with the PCOS set. I personally have gotten pregnant with Clomid and am on Femara now.

5) Take your vitamins. Start your prenatals now. They help. And they do wonders for your hair and nails.

6) Exercise. I know it sucks, but it really helps with the insulin resistance. You need 150 minutes of exercise a week, preferably 100 minutes of cardio and 50 of strength training. Muscles are good for fighting insulin resistance. This is the area where I really suck at meeting my goals.

7) If you’re overweight, lose some weight. A loss of just 5% can have a tremendous impact on your insulin resistance.
8) Use full fat dairy if you use dairy at all. The lower fat dairy has a disproportionately high level of androgen hormones which can exacerbate PCOS.
