copper IUD - period is due but only bleeding a small amont..

I also have the copper IUD fitted, my doctor said my first period might be a little of whack because of the coil.

Stressing about a possible pregnancy can make your periods late as well. Try not to worry about it too much as this could make your period later or you to completely miss it.

If the strings were in the correct place then having a guy come inside is like a 1% chance of getting pregnant even when you ovulating. If the coil moves then you have a higher chance of pregnancy.

I was told by the doctor who fitted the coil that I use other protection for the first 7 days and then after than I didn't have to. (however for me my doctor had trouble putting the IUD in, so she wanted me to stay on the pill until I'd had an ultrasound to check the positon and when I got the all clear I stopped the pill)

thank you so much for replying, I spoke to a doc again today she said its very unlikely that i am pregnant because I had the strings checked in advance and have had 3 neg preg home tests. I do another test this Sunday then book an app for a blood test but I was fearing so much that i have had an eptopic pregnancy but the test will pick that up I heard. I am going to do my best to relax and not worry but thats in my nature!

This sounds like my situation. What got me worried is that I've had my IUD for almost 3 years, and have been VERY regular regardless of what is going on in my life. However, I split up from my spouse almost 4 months ago.
25 days ago, to be exact, I had intercourse with a guy for the first time since. It was also 5 days after having my IUD checked (everything looked in place). It had been 3 months since having sex (yes, my ex and I had in until the end, lol), so I recognized that I might spot since it had been the longest in like 10 years I'd gone without. I spotted for a week after intercourse, and now, 25 days later, I am yet to have a period. I'm over a week late. I'm never late, and I never miss. To top it off, I Really was having pregnancy symptoms -peeing way more than usual, slight boob tenderness, this smell I get only when I'm pregnant or feel pregnant, and hungry, a little tired and more mood swings than usual. I realize that these are hormone related, and these hormones can be present regardless of pregnancy, but it still got me curious. I chalked it up to just an hormone imbalance due to the divorce stuff finally hitting me, as well as not eating as 'clean' as I usually do, which tends to mess me up. Anyway, I took 3 tests, all negative, but its funny that I just need to my period to get that sense of relief, ya know?
On my first pregnancy, I had a negative test, only to test 10 days later and be positive, so that must be why I'm hard to convince. The fact that has been 25 days since any intercourse, and the tests are negative, should be enough.

Some woman have low HcG levels which urine tests can't detect.

I would suggest you visit your doctor and ask for a blood test to be done to make sure 100%. A Blood test is much more sensitive at detecting the pregnancy hormone than urine tests.

You had 1 postive test. A postive is a postive. If you are pregnant, you need to have the coil removed straight away.
