i have been feeling nauseous for over two weeks, slight cramps most days. on the 6th three days before af was due i had a light period for three days. i normally bleed for 8 days. i had a corpus luteal cyst on an ultrasound about a week and a half ago as well. today i have had a clump of eggwhite cm streaked with red and brown blood come out. my dr doesn't think the cyst would cause the nausea. pregnancy tests are still negative. any ideas or experiences? tia
