Two weeks ago, this guy I really liked and I were messing around. We did not have sex, but he fingered me and popped my cherry. The next morning I began bleeding very heavily. It was not a normal period bleed. I had to change my tampon every two hours and it was constant and heavy. After two days it slowed and stopped bleeding. I was supposed to get my period a week after we messed around but it hasn't come. It is now two weeks late. Can popping your cherry mess your period up?

It sounds to me like you had your period. The breaking of your hymen will not interfere with your period in any way. It is common to have a period come earlier or later than normal and vary in heaviness.

First you have a Hymen, not a cherry, cherries are on trees or in jars. Next it is not a seal and to be honest many girls today have already broken their hymen long ago with tampons or just by exercise or other activties.

Many women have periods off schedule week early, week late. It does just sound like you started your period early along with perhaps the hymen being broke.
