On monday january 2,2012 I had sex with my boyfriend and he came inside of me; immediatly I went to the pharmacy to buy next choice. On january 9,2012 I had a very light period for about 5 days. 2 weeks after that I had unprotected sex again but this time I didn`t drink the pill, ever since then we`ve been having unprotected sex because this time we do want a baby. My normal period is a 33 day cycle it was supposed to come february 10 and till this day theres no sign of my period. I tested with an hpt the week before my period was supposed to start and the same week and all the test came out negative. My boobs have been tender for the past 3weeks but no period, should I just wait some more for a late period or should I go to the doctor??? I feel just fine, no kind of symptoms.
