Does the LH surge (monitored on opk) drop before, during or after you ovulate? My OPK tested positive yesterday but negative today- have i ovulated?

Ovulation today: The lh surge drops before ovulation. Lh surge from start to peak to drop lasts about 24 hours, and you will generally ovulate about 24 hours after the peak lh surge. Thus, you will likely ovulate sometime today. Good luck!

Yes: Many RE specialists will have you get a mid cycle ultrasound to look at follicle size and number. Obviously that's a more expensive way of doing thin ... Read More
