over the counter pregnancy tests are generally very reliable so it unlikely that you are pregnant. however i would recommend that you see your doctor just to make sure since you are having symptoms of being pregnant. your doctor may also do some additional blood work including a thyroid test to evaluate other reasons for the symptoms which you are experiencing.
i am now 14 days late i took a test this morning and it was negative. i haven't been under any stress and i've took several different test but their all negative. but breast are sore i feel fullness and bloating i also have dry mouth and nauseated at times. is it possible that i could be pregnant and still not picking up on the test? and if not whats going on?
