My last LMP was 01/10/2009 and i missed my next one* (02/10/2009, along with some mild abdominal cramping that has been going on since my ovulation which was on 01/27/2009! me and my husband were doin big things before, during, and after...... i also have swollen tender which are scaring me now because the little bumps around the areola seem to be expanding and getting bigger*(i knew they were there before , but never was i able to see them from afar* between the mirror and myself*) i have been having CM- throught all of this!!!! with fluctuating temps.... PLESSE SOMEONE HELLLP ME! I JUST DONT GET IT AT ALL! HELP ME TO UNDERSTAND ....
