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

Hi ask ko lang po if positive ba ako or hindi? Kasi 28 tapos na regla ko as in wala na talaga lumalabas then may nangyari samin ng asawa ko ng 29 at 1 wala kaming ginamit na kahit ano. Tapos after 1week nag pt ako positive pero medyo malabo pero makikita na na 2lines. Tapos nag pt ulit ako ngayon (jul 6) nag negative naman po.
