so last week Saturday I had my period. My supervisor asked if I was pregnant and I told her no. well she got me paranoid so I started taking test in the middle of my period I bled for 5 days all test were positive. I waited till I stopped bleeding and took another test still positive. I have my first intake appointment set up the nurse told me you can still be pregnant and have your period. so is this late implantation then ? got this today
