Before I say anything, I want to clarify that I'm not religious, and I do not intend to cause offence, just to provide information.
I'm assuming when you say 'popping your cherry', you mean stretching your hymen? If the hymen is stretched, it does not mean that you are not a virgin. The hymen tends to stretch over time, especially if you use tampons or do activities such as horse riding and cycling. It often happens as you get older without you even being aware of it.
The myth that the hymen is the only marker of virginity is very outdated and totally untrue. I understand that in some religions this is still widely believed and it seems to cause a lot of stress. Please try not to overthink it though and don't feel guilty.
