In march 2013, i had d&c (abortion) due to blighted ovum. i am 36 days from my last period and my pregnancy test is negative. please advice me. ?

When was test done?: Pregnancy is the most common cause of a missed period. If not pregnant, other causes of a late or missed period include: excessive weight loss or weight gain, increased exercising, emotional stress, having an illness, traveling, medicines (especially birth control pills), hormonal disorders, etc… a visit to one’s ob-gyn doctor is a good idea if symptoms are persistent, recurring, or worrisome.
