Okay, I'm driving myself nuts. I had very light bleeding about 7 days before my regular cycle was due.

Now, all of a sudden it's heavier and very visible. Both of my sisters had implementation bleeding, but now I think that it must not have kept it and I'm getting my regular period.

What does someone else think, I'll be very sad though.

I think you mean implantation bleeding, and it is more rare than one would think. Think of something as small as this little period (.) implanting in your uterus, do you think it would really cause bleeding? Nah, usually implantation bleeding happens when the egg implants right around the time of the normal period causing the period to be lighter and last significantly shorter.

It may be that you are just having a strange period, it happens to us more often than you think.
