Hello! My boyfriend of three years and I had unprotected sex about 7/8 times in the past couple weeks. My period was due the 15th of November, and I began bleeding the 10th. My periods are usually very heavy. However, this is seemingly very light. When I use the bathroom I will have drops of blood that seem very watery. However, there is close to nothing on a panty liner. The blood that drips when I use the bathroom seems to be a dark red, but on the panty liner it seems to be a very light reddish pink color. I am worried only because this is day three and many say implantation bleeding only lasts 2 days at most. I have been very fatigue, dizzy and nauseous, I have also found it hard to eat much. All of which are not like me at all. I FEEL pregnant. Could this be implantation bleeding?? Am I possibly pregnant??? Please help!!!
