hello i am a healthy 23 year old. i have normal periods and my husband and i have been ttc for two years. i have a 34 day cycle. when i was 12 dpo i started to spot light pink and then it progressed to a medium flow with tiny clots. i had a lot of pregnancy syptoms such as nausea , headaches, sore breast , moodiness, tiredness and increase in appitite. it could be my period i know but most of the time i bleed very heavy and cramp so bad the first day i cant get out of bed. i barely cramped and am not bleeding near as much this time. could i be pregnant? or am i wanting something so bad its all in my head? could it be stress maybe?
