Time of conception would be 10-24-12. About two weeks after conception I noticed my breast and nipples were extremely sensitive! I would not let my fiancée touch them! He noticed they also looked bigger. Putting that aside we moved on. I noticed sex was painful, and I didn't know why. My fiancée at about 3 weeks after conception pointed out I am sleeping a lot and I am eating more, and not liking things I usually do. I noticed I was sensitive to smells and would make me nausated. But I am not sick in the mornings. I haven't noticed if I pee more or not, but I noticed I have had more head aches. I thought I had my period on 11-2-12 and it lasted a couple days but than I realized it was extremely light and not really blood more like white pink discharge. But now at about 4+5 my breast are not as sore and erect. I can't really notice if I am bloated. I am trying to tell myself I am not pregnant to maybe not make it all in my head, you know? My fiancée is extremely worried, I am not as much. I have the mirena IUD and got it in January 2012 and I can still feel my strings. So shouldnt it be extremely unlikly i am pregnant? Just yesterday I had again a light pink discharge mostly watery, and I am expected to have my period in 2 days. I took two pregnancy tests at what would be exactly 4 weeks after conception. I read mirena can read negative when actually positive, and just all these weird feelings and symptoms are kinda worrying me. I don't think I am pregnant, but I am not for sure I am not either! Can symptoms come and go through pregnant? Cause I know my breast hurting was not all in my head! Please help!
