Line eyes?

E

I’m not trying to get pregnant. I haven’t had a period in 22 months because I was pregnant and then I’ve been breastfeeding my daughter for over a year. I started spotting on Saturday and am still just barely spotting today (Wednesday). I had sex once 2 weeks ago and then another time 9 days ago. We didn’t use a condom because I just figured there was such a small chance I’d get pregnant because I was breastfeeding and hadn’t had a period. I took these two tests on Monday which call me crazy but look like a supppper faint positive. Yesterday I tested again 3 times and they were all negative. So like, what’s going on?
