I have had an iud for 4 years now and never had a period, but I took pregnancy tests and all three said positive but the lines didn't show up all the way, one one there was barley a line. Am I really pregnant for could it be a miss read from the iud? I have ganed some weight and my uper stomic is tinder and my niples are really sore. I have been going to the bath room all the time, I am so confused. O yeah and my boy friend was cliped 7 years ago too. Please help

Some women find an IUD effects their periods, even by not having them.
If you haven't had a period in four years, I assume you have already spoken to your doctor about it, right?
Did you read the test results in the time required on the test? The IUD would not effect results, but if you didn't have enough urine on the stick or if you read the results after the time stated, it won't be accurate.
With your boyfriend having had a vasectomy, along with an IUD in place, odds of pregnancy are very, very slim.

See your doctor however and have it checked out. It will ease your mind to know one way or the other.
