I wonder did she have a chemical pregnancy? I had a chemical pregnancy a couple months back and I think this is what could have happened to Britney. It's where the embryo forms and implantation happens but it doesn't develop. You still get the positive test results and the early symptoms of pregnancy also. In Ireland you have to wait six weeks for a scan and the chemical pregnancy ends around 5 weeks. You bleed more and the pain is ten times worse than an actual miscarriage (have had those as well) she could have had one of those. It's common for women in their late 30's early 40's.
Either way it is traumatic and she will need help.
