Im a bit concerned

I was recently fingered for the first time. This was the first time anything more than a tampon has been up there. After our activities i went to the bathroom to find blood all in my undies. Im assuming this was my cherry or like my hymen tearing. But i have been lightly bleeding ever since it happend. ( 2 days ago) and im a little bit worried. So did something go wrong or is this normal. Please help
