great to see you! Sorry about the misleading signs
did you chart your cycles? If you didn't, you may have ovulated later, not at all, leading to a misleading test day. If you did and are sure of O day, you may have a lutial cyst. I had this a while ago and was very confused. I had a very clear ovulation, good timing but was 30+ dpo and rising with lots of symptoms but negative tests. I spoke to chart experts who couldn't understand it, even my doctor couldn't understand it! In the end, we *think* it must have been a lutial cyst delaying AF.
Good luck and I truly hope you find an answer soon - hopefully a happy one, if not then atleast an answer which can help you move on...
