So, for three days I 'spotted' (only when i wiped there was blood) on the 4th day I bled lightly for a few hours, then back to spotting then it was all done the next day. on days 1-3 my boobs hurt very little and i felt easily warn out. day 4 my boobs hurt more then ever and i was so tired. was this a strange AF? Could this of been implantation bleeding? Should I take a test? If so when?
