I still can’t figure out why people ask if they’re pregnant. We won’t be able to tell you 100% no matter what. You could have been late for a number of reasons that have nothing to do with being pregnant. And any implantation bleeding would be light and usually not bright red. If you were pregnant and heavily bleeding red, that would indicate a problem. Since you’re bleeding now, you’re probably having a period. If you experience any intense pain or unusual amount of cramping, go to a hospital and explain that you think you may be pregnant. But it’s unlikely. Take another test to be sure. But odds are, you’re period was simply late.
