Hi! My husband and I recently decided we want to start TTC baby number 2 so I had my iud out March 25th 2013 after having it 9 months. On March 28th I started a regular 4 day period, felt like I ovulated the day I should have (had a tiny bit of brown discharge during ovulation) and its now may 15th and I haven't even spotted since march. I have taken multiple pregnancy test and all negative. How long should I wait with no period before going to the dr? My periods have always been 28 days and VERY regular.
