last month i got the mirena coil removed and had period straight away for 8 days ended on the 30th july
​i am now a week late on my period having cramping bloating nausea dizziness always tired frequnt toilet and bowel movements 
​i tested a week ago and BFN and i also had a blood test on tuesday and the doctor hasnt wanted to see me so i take that as another BFN
