On march 11, 2013 i undergone d and c due to blighted ovum at 7 weeks. Took some meds and completed all of them. 2Weeks after i had unprotected sex twice with my bf. Then 2weeks after that i had my 1st cycle post d and c. But it was unusual. Had it shorter than before. About 4days only. And the discharge was.brown in color, not red or pink. Could it be old blood? or implantation bleeding? is it possible to have that long? I only use 1pad/day and not totally soaked. Right now, almost 2mos post d and c, i feel nauseous all the time esp after eating. Lightheadedness when getting up. And sleepy all the time. My breasts are not swollen or tender but i think i can see montgomerys tubercles... if i am pregnant, is it safe?
