okay...

I've been on birth control for almost three years and Seasonique for a year. Because of this, I only get my periods 4 times a year. I've been sexually active with the same (one) guy for about 2 years.

During the last week I've had a pink discharge (obviously blood) that comes out either mucusy or clotty. Sometimes it's all pink and sometimes it is mixed with a clear or white colored substance.

I'm also having slight cramps and getting headaches.

I've had "break through" bleeding before, but this is different. It's never purly period-like blood...

I'm starting to worry that something serious could be wrong. I go to my gyno regularly, the last time being in March. My pap-smear came back normal.

I have no other symptoms... no breast tenderness/enlargement.

Could this be the early signs of pregnancy (implantation)? miscarriage? or just a different kind of "break through" bleeding?

any insight would be greatly appreciated.
