Hi,
I have been on the Mirena iud since April 2010 and have always had a normal menstrual cycle. My last cycle was in April, but it was very light and was only for about 1-2 days. I missed my cycle last month, but have been having menstrual cramps, headaches, sore and painful nipples, pains in my lower left abdomen and back pains for 3-4 weeks now. I took a pregnancy test about a week and a half ago, but it showed negative. Can I still be pregnant?
