When exactly was ovulation?

Question

Ok my best friend is TTC. She is using one of those clear blue fertility monitors. She got a "peak" on The 3rd and again on the 4th. When exactly did she most likely actually ovulate?? The 3rd or the 4th??

Answer 1

Actually, most likely on 4th or 5th. Normally you get a LH surge 12-36 hours before ovulation, so by the time it happens, the LH has normally gone back down again. But having said that, I got a peak the day after ovulation this month (I know it happened because I had an ultrasound that day by accident, and my doctor saw it!) Aso remember that the first few months of the CBEFM is not totally reliable as a guide because the machine is still learning her body's hormone levels. Next month she should only get 1 peak day and by the 3rd month it should be 2 days high, 1 day peak, and then back to low.

Answer 2

She most likely ovulated between the 4th and the 6th.  Fertility monitors tell you when you're fertile.  They don't tell you when you ovulate. The idea is to have s*x when you're fertile BEFORE ovulation, so that by the time the egg is released (ovulation), there is already sperm there waiting to fertilize it.

Answer 3

You get a peak about 12-24 hours before you ovulate.  Usually, I think it's after the last positive reading.  Her surge probably lasted 2 days.  However, I've heard some weird stories with OPKs not working quite like is expected.  She probably ovulated on the 4th (maybe later in the day).  If you combine OPKs with charting on a site like fertilityfriend.com, it can make things a lot easier.  Then, she could keep BDing until a negative OPK and a temperature rise.  Good luck to her!
