January. Usually my wife period cycle is 24 days. But this time on 26th day on 1st feb there was light bleeding which last till 3 feb. It was lighter than normal period. Today on 8 feb when did home urine test was negative. My questions are. If 1 to 3 feb was implantation, after how long home pregnancy test will be more accurate. & can I still try to conceive if not sure about pregnancy. Because next conceiving date is around 10 to 12 feb.
