is there any possible that at your 4rth week of pregnancy that your pregnancy test is two line but the second line is paintline?

it was taken 2days ago , pero neregla po ako last month like normal menstration po , then last 2weeks ago nagkaroon ng brown discharge .we are active on seggs is it posible po ba na buntis ako or its just too early po para mag test ako? i run 3x of test and same lang po mga result .
