And frequent of headaces throughout the day, please reply with any helpful information And I don't really have periods because I have the rod in my arm but I had the rod implant after I had sex.
If you had unprotected sex then there is, of course, a chance of pregnancy. The only way to find out is to do a test I'm afraid and then go from there. As it has been several weeks a test would be accurate.
