How long did it take after your miscarriage to get your period? My dr told me that if it doesn't come after two weeks to go back and get blood work done... It's been two and a half weeks since and I still don't have a period. Should I go back and get the blood work or should I wait it out? I should mention that I have had some light pain on and off on my lower left side and worried that it could be an ectopic? Also, I have taken pregnancy tests and they come out negative... If it were an ectopic wouldn't it still say positive?
