4th baby but 12th pregnancy and I’m scared

Sophie

I think I am 13dpo and due on the 6th of July. This baby was not planned and I’ve spent the last few days being really concerned about how having 4 kids will affect my current children’s lives and the opportunities that we can give them. When I woke up and took another test this morning (bottom test in the picture) I thought that it wasn’t as dark and I felt really sad that I could potentially be having yet another early miscarriage/chemical pregnancy. What do you guys think?
