I had my period last week and my bf and i had sex the day after my period stopped which was two days ago. he hit the iud in the middle and it hurt like hell. He said he felt the tip of it. I already have one child. Im 18, and freaking out. I know that it has only been two days but the day after we had sex i woke up feeling almost like i had a hangover and i felt the same today. I have no energy. Dont feel like eating but cant really get full. Im sooooooo tired. And i just feel funny. Help please?!! whats wrong with me!!??
