i had sex about 12 days ago. 2 days ago i started spotting brownish blood (not even enough to fill a liner, and btw this has never happened before) then, this morning I began to bleed heavier with some mild cramping for a while. now my bleeding has dwindled to light bleeding every now and then, but definitely not like my perioud usually is. i would to kno if anyone thnks this is deciduous bleeding. i have had a higher temperature for the last 4 days along with constipation, headaches and extremely tender nipples. if anyone else has experienced this during their pregnancy could you help me out?thx!
