9dpo?

Bel
I'm wondering are these really strong lines for 9dpo? I have a regular 28 day cycle so if anything my ovulation day was only a couple days off track. I'm not even due to have my period till 4 days from now. I'm thinking I might be further along or twins? 
I took the picture only 4 mins after testing. Tell me if this is normal? 😅
