Hey! I am 15. On April 1st, I had sex with my ex. My last period started on March 19th. Maybe about a week after I had sex, My appetite increased greatly and I began feeling nauseas, dizzy, tired, and weak. On the 14th, I had very light bleeding. The next day the bleeding was a bit heavier but not near what my regular flow is. Today the bleeding has been light again. Could this be implantation bleeding? Do these symptoms sound like pregnancy symptoms? Please help; I am really worried. Thanks. -jor
