I am now 12 days late for my period and have a copper coil fitted. I have done 5 HPT - all negative and one family planning clinic test - the last one being done 2 days ago. My symptoms are dizziness, nausea, tiredness, emotional, frequent urination, thirsty. My doctor says that hpt in this day and age are very accurate and that I am not pregnant. She has tested my blood for anemia and diabetes (although not pregnancy?????) which came back negative. She says sometimes periods just are late and if I still haven't come on in a few moths to go back! I feel like crying, what is wrong with me and why is my period late if I'm not preganant? By the way my coil is still there.
