My period is suppose to start on the 7th I have brown discharge now could it be implatation bleeding I did have intercourse on my fertile day

Anything is possible. However, implantation bleeding is really very rare. It is more then likely just the beginning of your period. Unfortunately you are in the waiting game now. Wait for your period. If it doesn't come, wait a week, then take an hpt.

But why am I having brown discharge its like old blood I had a miscarrigde sept20th 2007
I been trying to get pregnant

Its not uncommon to have brown blood, before the beginning of your period. I have had periods in this way since I started having periods. Implantation bleeding does happen, buts its very rare. If you think about how tiny an egg is, it is understandable how it wouldn't cause bleeding, or very much of it, when it implants. Typically, if its implantation bleeding, it won't appear more then just wiping, and be scant then. However, as I said, it does happen,and every woman is different. That said, the brown discharge could be from anything. Our bodies like to throw us through a loop sometimes. Like I said, you'll just have to wait and see at this point I'm afraid.

Afraid of what? Your scaring me so are you saying it could be implantion bleeding?

Its not blood like its sticky and brown I don't need to wear nothing its present when I use the bathroom I think I'm pregnant

I'm not telling you to be afraid of anything. It's a figure of speech. I'm saying you have to wait until your period comes or doesn't.

There is no way for me or any one else to know if you have implantation bleeding or just bleeding. Because like Buggage said, it's rare. Only a Dr. can diagnose you with pregnancy and properly explain and related bleeding. I know what its like to be trying to get pregnant. I got really anxious, month after month, year after year. You very well could be pregnant. I'm not saying your not. However, don't get mad because people are not giving you false hope. Unless you tell us you had positive home test or you are several weeks late and puking you guts out, we are not going to tell you that you are probably pregnant.
