im taking tests and they are negative but i have a few questions. since my miscarriages in march & april, my periods have been every 15-18 days. well, it's day 19 and i still havent gotten my period. my nipples have that "burning" sensation with the touch of anything, which was my first symptom the first time i was pregnant. then im nauseous as all get out. not sure if it's left over alcohol in my system from saturday of labor day weekend or morning sickness symptoms. im miserable. we have not had sex without pulling out since my miscarriages. all we rely on is the pull out method and occasionally condoms. what do you think?
