1st time in this month i was missed my periods n my vagina was dry y? is it the symptoms of pregnanacy or anything else?

Maybe, maybe not: 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.
