??? Too soon?

Lindsay • After 8 miscarriages,we got our little miracle in Feb 2016. My little Aidan! Currently now expecting baby #2!
So I took an opk 2 days after AF and I'm seeing a faint line. I would post a photo but phone just comes up blurry. Is it normal to detect an LH surge that early. I don't have a consistant cycle. Average is like 30-35 days. Think it's too early to see a line but why would it be there? Any comments would be appreciated ✨
