Opk positive at 6Dpo

Chantelle

I am currently 6DPO (tracked)

And today I took a opk test with my friend (trying to show her how it works, she’s ovulating and I’m not so was gonna show her the difference in lines)… but mine came up clearly positive?? I’ve heard you can get a LH surge before your period is due?? 😞 feeling bummed.

Has this happened to anyone before?
