What is going on

Hi,

Long story short I was on birth control for 13 years, stopped it in July to get my cycles back so we can TTC. My cycles used to be 28 days, now they’re 21.

Here’s what I don’t understand. I am on day 3 of my period and decided to take an LH test out of curiosity. How is it already rising while I am currently still on my period?! That doesn’t make sense to me, like it’s too early for that.

I’ve also had 2 distinct LH surges 4-5 days apart each cycle for the last 3 cycles so am I ovulating twice?

What in TF is going in here 😅
