Today, Jan 11, I am 18days delayed period. I had 3 negative test already. My last period was Nov. 20-27. My cycle length is usually between 31-34days the most. I dont have any early sign or symptoms of being
pregnant. I gained 3 pounds since I was on a vacation last month. There are also times that I am missing my period especially of I am sexually active. Is it possible that I am pregnant?
