My husband and I just got married earlier last month. Ever since then I've been sexually active with him (was my first time). Prior to us getting married I started keeping track of my period; they were starting every 15th of the month. However the month I started being sexually active my period started on the 16th. Today is another month and it is the 18th. I still have not gotten my period. I have sensitive breasts and mild symptoms I tend to get before I get my period (tiredness, bowel movement, etc). Could I be pregnant and is this normal? How soon after a missed period am I able to take a pregnancy test? Maybe I'm thinking too much... P.S. We use no protection, just pull out method by the way.
