樓主,my case is also very similar to yours.
so i can understand, the nurse also said it gone so clear and nothing need to do.
so i think it is somehow like M, as 我流血 in week 4-5.
我老公 also more disappointed then me at that time, but now we are add oil to do iui, just start it.
so sad to hear that. I understand what you are feeling. but sometimes it happens, when it is yours, it is yours, but when it is not, all we can do is just to let it go.
