help?! breastfeeding a maybe a positive?

C • Married❤️ Boy Mom💙 currently expecting #2🤰🏻
Okay, so a week ago I got a slight positive on a test. However, on every test after that they have been negitive. The last three days there has been a slight positive. They are possibly getting darker. Obviously, the test would never react if I wasn't pregnant but I'm still worried. Anyone have this experience? I should also mention my son is 7 months (almost 8 months) and breastfeeding. Would that effect it?
