L H surge (twice a month)

diem - August 7

Does anyone else out there have 2 LH surges per month?
This is my second month using OPKs where I've had a surge at cd 10.
Last month I had a surge on CD 10 and on CD 21. This seems early and late to be surging. It looked as though I actually ovulated on the second one but that gave me a very short luteal phase. I wonder why I keep surging twice.
Does anyone have any info on this|?

i found this on the internet. you can type in ovulation twice in one month and read it if you want to but here is what i found:

Fertility and Sterility
Women may ovulate more than once a month, suggests a Canadian study that overturns conventional views on the human menstrual cycle.

The findings may explain why the rhythm method of contraception is so unreliable and could lead to improved, targeted fertility treatments in the future.

Ten per cent of the women studied released two eggs in the same month. And all the women examined by researchers at the University of Saskatchewan in Saskatoon, Canada showed at least two waves of maturing eggs in their ovaries in the same month.

Traditionally, it has been thought that ovulation takes place only once in every menstruation cycle. A growth wave of 15 to 20 egg-carrying cells called follicles occurs before ovulation. One follicle will become dominant while the others die off.

"It's been assumed until now that women have just one wave per monthly cycle, leading to one ovulation, but nobody has actually carried out detailed analysis before," said Roger Pierson, who led the study. "In fact, all the women in our study had at least two waves and 30 per cent of them had three."

Fertility treatment
The team carried out daily, high resolution trans-vaginal ultrasound examinations on 63 women with normal menstrual cycles who were aged between 18 and 40. Over six weeks, the women's individual follicles were measured.

During the study, 50 of the women ovulated only once, but six ovulated twice and seven not at all. The next stage of the research will be to find out why some waves lead to ovulation while others do not.

"We don't know why some waves lead to ovulation and others don't. But we want to utilise our new understanding of the menstrual cycle to be able to carry out better timing of in-vitro fertilization," Pierson told New Scientist.

Progesterone secretion from the corpus leuteum - a temporary hormone-producing gland that is formed at ovulation - may cause a surge in a reproductive hormone called luteinizing hormone, he says. This might have an inhibitory effect on further egg release during the menstrual cycle, which could explain why some of the women did not ovulate twice despite having two growth waves in their ovarian tissue.

It may be possible in the future to harness some non-ovulating waves into releasing eggs for couples having trouble conceiving, he added.

The unexpected findings may also explain why the conception rate for non-identical twins is as high as 10 per cent.

"It could be that more than one dominant follicle is produced during a wave or that dual conception arises as a result of two waves in a cycle releasing eggs," ventured Pierson.

i have also found this:Q: What could interfere with my test result?

A: If you are already pregnant, have recently been pregnant, or have reached menopause you may get a misleading result. Some prescription drugs, such as menotropins for injection and danazol may affect the results you see. Please consult your physician if you have any questions about prescription drug interactions.


positive OPK sticks within a week??

Question: This is my second month using the OPKs. Last month I never seemed to get a positive reading from the OPK sticks. My cycle was all out of whack, and next thing I knew AF arrived. This time to make sure I would catch my surge, I began testing right after AF left. A week from today it was positive.. I was sooo excited. I went ahead and checked on Wednesday - positive again. From there it dropped off to no line at all. So, we BDed tons and I assumed I ovulated. Just because I'm super curious and skeptical, I kept using the sticks. Sunday it was positive again (both lines were equally dark once again). Monday - not quite positive, but almost. Today, no lines at all. Is it positive to O twice?? or is my body just playing tricks on me? I have no idea how many DPO I am and thats driving me crazy. Any ideas would be awesome!! Thanks :)

No, you *can't* ovulate twice in one cycle except in the case where both ovulations are on the same day (this is where fraternal twins come from).

An ovulation test can turn positive if you are pregnant, but it would have to be *more* than a week after ovulation, so that's not possible either.

I suspect it's the third possibility... An ovulation test doesn't tell you when you *will* ovulate. It tells you when your body is *preparing* for ovulation. Sometimes, you will have an LH (luteinizing hormone) surge (which is what the test measures), but then you *won't* ovulate. Then, you can have a second LH surge that *does* lead to ovulation (or maybe not again--and possibly even a third, etc.).

If you have more than one positive test on an ovulation kit (more than a day, but no more than a week apart), it is the *last* one that is probably ovulation.

However, I would suggest you skip the ovulation kits altogether. You can tell when you are ovulating more accurately (and *cheaper*) by charting your fertility signs. Please read _Taking Charge of Your Fertility_ by Toni Weschler. It has all the information you will need.

Wow! Thanks slowpoke!
This is great info. Way more than I expected to see. I am going to the DR. today. I wonder what he'll say.
