Very faint control line on pregnancy test, am I pregnant?

So I’ve been feeling extra tired, bloated, and gained a few lbs out of the blue. I’m 5 months postpartum and still breastfeed my son as well as pump. I did notice my milk supply drop slightly so I took a test. The test line is dark but the control line is faint; what does this mean?
