Jody
So I had my iud taken out November 3rd after 5 1/2 years because we decided to try for baby number two! According to glow my fertilite days were the 1-6 the 3rd and 4th being the most fertile days! We had intercourse every day that week and now here I am on the day im suppose to start my period and nothing!!!! No signs no nothing should I test? Or wait a few more days? Could I really get pregnant that quick?? Ahhhh wasn't expecting it this fast
