thanks so much for your answers..

Yes, you're right.. I dont need to be taking the morning after pill.. I was irresponsible and I am most definitely NOT ready for a baby.

i am a little worried about it because I think I might want children some day (far away lol),, and my mom needed help but got cancer from the hormones and I don't want that to happen to me.
I guess it's good to know that it might not be anything serious. thanks!
