Am I pregnant? I am on the iud And 8weeks late?

1) don't keep repeating the same post. You need to be patient. Posting the same thing over and over again won't get you a quicker answer.
2) sometimes the iud can cause you to stop bleeding altogether. If you have any reason to believe you may be pregnant though, take a pregnancy test and/or see your dr. no birth control is %100 effective so there is always some chance of pregnancy.
IUD - Intra-Uterine Device or IUS Intra-Uterine System (http://www.birth-control-comparison.info/iudinfo.htm)

I have the IUD and don't have my period at all. That's mostly the point of the IUD. I wouldn't worry, but just to be sure you could always take a pregnancy test.

Some birth controls can be counteracted by antibiotics. I don't know enough about the iud to know if that could be the case or not. I would suggest going to your doctor and asking them. They'll be better at helping than anyone here, since they can run tests and see you in person.

And, while taking a pregnancy test is a good idea, you should be aware that some women can get a positive answer while on birth control. Some birth control methods prevent pregnancy by releasing the pregnancy hormone and tricking the body into thinking it's already pregnant, which can cause a positive result on home pregnancy tests.

Are you pregnant? Pee on your keyboard and I'll tell you. All joking aside, it is impossible for us to tell you whether you are pregnant. No form of birth control is 100% effective aside from abstinence.

What IUD are you on? Does it contain hormones? How long have you had the IUD in place? Have you taken a HPT using first morning urine?
