Planning a Baby  Discussion Forum

Hi Archie & others,

I have a quick question to ask- Approximately, how long does it take to notice a thermal shift in the body tempertaure, after you see the LH surge ? I mean, how many days after you see the surge, you notice a rise in the body temperature?

I know, when you see a noticeable change in the temp, it means you have already ovulated....but I want to know- how long after ovulation this thermal shift takes place ?

I am confused ! Please help me understand this temperature technique.
Anny replied. Dear Archie & SK,

Thanks to both of you- thanks for clearing up my doubt.

Archie- I will keep track of the temp drop and act accordingly.

Archie, One more thing- when I see the surge on a particular day, should I repeat the test on the same evening? (I remember having read this somewhere in one of your posts.) If I see the surge of the same intensity even in the evening- what would it mean ? Or should I expect to see some difference in the intesnity of the color ? Guide me please.

Thanks in advance. archie replied. it will vary from brand of opk to opk.
if you get one that detects ovulation in 24-36 days then right next day of surge you are likely to experience drop in bbt and in about a day or two rise of bbt. When you see drop in bbt is right time to plan intercourse until it goes high.
archie SK replied. using OPK when you detech a surge that means you are about to ovulate and that can happen within next 24 hours.
So you can expect your body temp to rise after that it happens once you have ovulated.
