Can implantation bleeding occur the day your period is due?can I take a pregnancy test while bleeding?

Yes, depending on when you ovulated, it can... although most women never notice any bleeding associated with implantation. Some spotting or light bleeding can occur in early pregnancy, sometimes thought to be a period. To have the most accurate result, best to wait until you miss a period. You can certainly try one sooner; some women do get a positive quite early.

It is possible, but I'd wait to see if it's going to get heavier like a normal period. It's likely you're period is just starting. And implantation bleeding is usually spotting and a pinkish or brownish color and only lasts for a day or so. Also, I see a lot of people on here thinking they have implantation bleeding if you read up it only happens to a small percentage or only a small percentage of women notice it because it's so light and not red. Most women don't even notice or even have it.
