How soon after a lost pregnancy can I expect to see my period? A month ago I lost a pregnancy at 21weeks 4days bled for a week and since I have been having on and off abdominal pain headaches and mood swings, my husband want to try again soon but am worried because I have not seen my period I started having unprotected sex a week ago, took a pregnancy test today and it came up negative. What can I do and what steps can I take to try again? This is the second pregnancy I have lost in 4yrs at second trimester and am 39yrs old.
