I’m really struggling. This is (was) my fifth pregnancy and for a week before I did a pregnancy test, I had all my usual early symptoms - sore boobs, tiredness, nausea, slight breathlessness. I did a couple of tests which showed negative. By the following week, I was also having strange food cravings and bought some more tests of different brands which were positive. I was over the moon. The night before last I started bleeding heavily. My periods always start light for a couple of days and then go heavy for a few days and then light again for the last day or two. Having had two miscarriages before, I knew I was flushing my baby down the toilet, but went to hospital yesterday to get checked and hoped I was wrong, or that there might be a surviving twin or any of the straws we cling to. The early pregnancy unit wouldn’t see me unless I’d been referred from a and e. I sat in A and E for hours bleeding away my baby and was asked to provide a sample. The triage nurse said the test was negative and I could never have been pregnant as it would show a positive test for 21 days. I’ve never heard this. I told them I’d done a number of tests that had shown positive, that I’d had pregnancy symptoms and that this felt like other miscarriages. They asked why I’d done multiple tests if I was certain. I know I was pregnant. I’m gutted I lost the baby and it feels worse being told he/she never existed as though I just invented it and wanted to spend the day in casualty crying my eyes out. Has anyone else heard this 21 day thing?
