Probably an indent

Aislin
Still far too early to be testing really. Someone really needs to hide the pregnancy tests from me until 12dpo.... But they're so cheap and I want my rainbow baby so badly :( 
This is 8dpo... IF I even ovulated I had some wacky results on the OPKs this month. There's definitely a faint line but I think it's an indent?
The only thing worth noting that's different this month is that my boobs are normally sore immediately post ovulation and so far nothing, nada. But I've never heard of not having sore boobs being a symptom. 
Thoughts?
