Ok everyone... little history first, so I hope you will get a better understanding of my body (maybe a better understanding than even I have).... I got my IUD removed, after 6 years, on August 6. I had a period in September, like normal. And now I'm late and am getting BFNs. How long do I wait for AF before I call the dr? My husband keeps telling me to stop testing, but I don't get why it's not positive if I'm this late... 6 days late now.... opinions? Thought? Input?
