Good day!! Help me. I already take a pregnancy test 2x. 1st 3 pt in one time(last week, same brand) then yesterday 3 pt in one time again, same brands but this pregnancy test yesterday is not the same as the brand that I used last week. All PT are negative. No faint lines. It only has cleared one red line. BUT I AM DELAYED 😩 why?? I don't know why? I am preggy or what? I was so stress this past few weeks until know. My last mens is December 23,2020. My intercourse days(sex days) is December 30,2020(withdrawal) and January 19,2021(withdrawal) and January 29,2021(no ejaculation,no semen)
