I had the Mirena coil removed on 12th December. (had it for 5 years with occasional light bleeds). On 15th December I got a period which was fairly heavy to begin with which was fairly normal to how I remember them being before. According to my tracker I am now 7 days overdue. I have had some of the symptoms - sore breasts, mood swings - but no period (and negative preg tests). At what point should I start being concerned about the lack of period? Do I just see what happens over the next few weeks/couple of months? I'm 38 so slightly paranoid about what my body is doing as I am hoping to conceive if I can.
