How long does your LH surge last?

Jordan

First time <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a> in 4 years. I truly can not remember how long my LH surges lasted. I typically have 30-35 day cycles.

Two positives in two days. I read it could last up to 72 hours, but want to know your experience.

Did you have sex on the day of your positive or the day before & day after?

We had sex yesterday & will be having sex again today, for just incase!
