Could I be pregnant?

I’m not one these girls normally.. but I’m 12 days late for my period today.. I took a test exactly a week ago.. this is the test after looking at it at exactly a week later.. I know you’re not supposed to look at it after a certain amount of time but I got curious.. I’m on the patch.. I had my first period before I took the patch off for a week which was supposed to be my period week.. I’m scared of being pregnant again.. I already have two kids.. my youngest is 3 months my oldest is 18 months.. I’m just hoping it’s my body trying to get used to the birth control.. this was supposed to be my second period since being on the patch and second one since have my son..
