I ovulated on September 19 and I had what I think was implantation bleeding 5 days before my period was due. It only lasted a 1.5 days it was dark brown blood. Only seen it when I wiped tho. My period was due October 1st. Still no period and negative test. If I had implantation bleeding on the 27th should I wait a few more days to test?
