I missed my period, which should have started at the beginning of the month. Then I began to have some pregnancy symptoms but all the home tests I took came back negative. Now today, 18 days from when I should have had my period, I began bleeding. It's bright red and nothing like what my period usually is. I have some pretty bad stomach cramps also. Does this soud like a miscarriage ? I just moved so I don't have a new doctor yet, should this be an emergency room visit?
