My period was due on monday, and its saturday....no period. I have taken like 6 tests at home, and all say negative. We have been trying to conceive for over a year and nothing.... my period is always on time, except last month i was 2 days late.... Any ideas? Oh and i am not feeling any symptoms of prego, or having a period...its like neither exist? I guess maybe a little tummy aching, and some nausea, but thats it. Help Please
