Pregnancy Info HOME

Hello, I had a Mirena for about 10 months (from March 2012 - January 30th 2013) on the night of removal my husband and I had unprotected s_x starting that night up until this day. The last time I got my period while on the Mirena was back in September. After the Mirena Removal on January 30th I was told by my DR to begin my BC pills that Sunday (and to use protection) so I have been taking them faithfully as of that day. Lately, I have been feeling nauseaus at random times, alot of headaches (last one lasted 1 full week), always hungry, especially at night. After I finished my active pills (started Sunday) My period showed no sign of coming (I always have sore br___ts) but it ended up coming on Thursday and by Saturday morning it was gone. (started very heavy, intense cramping). I have also been very tired can barely wake up in the morning, some nights I can't sleep, my br___ts feel heavy some days, I have taken 2 tests prior to my period arriving and they were negative. The weirdest part has been my 2 day period this has never happened to me usually 4 to 5 days while on BC. Could this be pregnancy? Is it too soon to tell?
