I was supposed to get my period this morning, August 27. When I woke up, which is normally the time that I first noticed my regular period flow, I noticed that there was no blood when wiping after using the restroom. I inserted a tampon and went to work for two hours, only to find one taking the tampon out to very small droplets of blood. I normally have a pretty steady flow, replacing my tampon every 3 to 5 hours on the first day of my period. Throughout the whole day the flow has been abnormally light. I was wondering if someone could give advice as to whether they think this is implantation bleeding or just a very abnormal light flow for the first day of my real period.
