roughly 2 weeks ago passed a blood clot , wasnt big at all .... slight bleeding after but nothing really , since then , ive been feelin more tired than normal , nausea comes and goes within the last week or so ... just within the last few days my breasts have gotten really sore and heavy like . my period is due within the next 2 days , and i havent had my normal cramping or bloating .... nothing , not even my horrible mood swings i get from PMS ... im not sure what to do , i dont have a doc , and can barely afford a home pregnancy test ... what would you suggest i do ?
