I am about 6 days late on my period. Every day since my first late day the tests came out negative. Yesterday was my 5th day being late… me and my husband had sex and after I went I wiped and I noticed I was lightly bleeding. It’s not normally like as if I was starting my period. It was a little redish- pink with streaks.. and now it’s day 6, no period and no spotting. Could this be implantation bleeding? And when would you recommend to take another test for a positive result?
