HI Archie, SK & all,

As I wrote earlier that I detected the LH surge last friday( 22nd april). The surge line was exactly similar to the reference line. My hubby asked me to repeat the test the following day(On Apr 23), we just wanted to see what result it will show- and to our great surprise, it showed the LH surge again and this time definitely darker than the earlier day. This time the surge line was distinctly darker than the ref. line. My hubby was making fun of me that I have too much of LH in my body :-) lol !

According to the booklet, if the surge line is simliar to or darker than the refernce line, then you have detected the surge. In my case, I noticed both the things.

So my question is- is it possible to see the surge continuously for 2 days ? Because I remember having read one of Archie's messages that the LH Surge generally disappears in 12 hours or so and the maximum time one would find LH surge (with repeat test) is less than 18 hours. So if you see the LH surge on one day then it's not possible to detect the LH surge again on the second day. ( by the way,I performed the test at 4 pm on both days.)

I would appreciate if anyone can clear my doubts.

Thanks,

I am not sure what post you referring to. As far as I remember the LH surge is less likely to be detected on the next day but not impossible. It may be that the earlier day you were about to have surge and next day it may have been a few hours actual surge. It's not that LH comes and stays for those hours, true that it disappears quickly but urine test can be weak positive for a few days before actual LH surge. It may sound ridicule but it's not that strange to imagine that someone would find weak positive somewhat clost to reference line and actual surge is darker than reference line. When a reference line is made is always average from number of studied samples (people) before deciding on how much amount of hormone will give rise what intensity of color.

If you have had intercourse on the first day of your surge (previous surge) and also going to have for another 3-4 days you should be fine.

But if you detect positive test for next day then certainly there is something you need to bring to attention of your gynec in case the cycle fail to get you pregnant.

LH surge can be detected as long as 24 hours or little plus. I have always referred that the day one gets surge should repeat the test same day evening to assure that the intensity grows or stays the same. If the intensity of evening is better over afternoon then sure surge is about to take place or taking place. If the intensity is weaker to afternoon or disappeared then surge was happened,and is great time to perform intercourse.

An egg (ovulation result) released can not survive longer than 12 hours.

Disclaimer: regardless what's said do not forget each case is different and some variations can be found.

Should you have doubt place a query and lets see.
