Faint positive??!

I'm either 10 or 13 dpo today. I had 4 days of positive OPKs this month and I wasn't sure when to start counting, so that's where I am with that. Lol My period has yet to start, and this morning I got this. Hoping I'm not seeing things and this line gets darker! I had a chemical pregnancy last month, so I really don't want to get my hopes up until I see a dark dark line!
