I have had a regular 30-31 days cycle for over 17 years I removed my 2nd IUD (paragard no hormones) on july 9th my last day of menstruation. My August period is 7 days late I took a pregnancy test on the 9th it was negative had anyone had a change with period how much longer should I wait to test or for period to come? I do have backpain, sore breast and ankles/feet are swollen that's usually my period symptoms but I have been like that for 3 weeks and still no period any common experience?
