When me and my husband decided it was time to have a baby I had my Mirena IUD removed in september I spotted for a week then had a period on the 25th and it lasted 3 days then i had another period on October 25th and it lasted 3 days... Before i went on birth control I had irregular periods but while i had my IUD I only had 2 periods a year, which the doctor said was completely normal. I have taken pregnancy tests that are sensitive and then some generic ones all have said negative but i have been extremely nauseated and had cramps and gas and constipation... I am a migraine sufferer but have only had 2 in the past 2 weeks when i normally have 4-5 a week... my breasts don't hurt that much but the areola seems to have darker pigment to them... Is there a way that i am pregnant but not getting a positive result?
