Second IUI testing

Hi ladies, I swore I would not test until this Friday (my second IUI was 8/29) because I was devastated last time when that faint line faded to negative and never came back. Well I tested yesterday morning and say the faintest line but wasn't getting my hopes up. This morning I tested and that line is darker!! I'm still trying not to get too excited, though that is easier said than done. I'm 10dpiui, 12dp trigger today. Here are the side my side tests.
