11 days ate

I am 11 days late but when I take a pregnancy test this morning it came up negative I have all the signs and symptoms of pregnancy but I’ve also had complications with home test before because my HCG levels not being high enough I don’t have medical insurance to get a blood test done should I go to the emergency room🙎🏻‍♀️💁🏻‍♀️🤰🏻
