I had the mirena coil removed Dec 14th 2016 after having it for around 8 months, my periods were always irregular and heavy so I couldn't really keep track, I think the last time I had any sort of bleed (sorry tmi) was the start of December. I haven't had any contraception since and we have had unprotected sex since, I've had sore breasts/slight nausea/slight and mild cramps in ovaries and been tired/headaches for the past week or so, not even the slightest bit of bleeding since and no sign of AF, I've done around 4 tests and all BFN, when should I take one next? I feel if I was to be anything I would be between 8-13 DPO
