How long does your LH surge last?

Jordan

First time tracking ovulation 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!
