Hey everyone , I recently started TTC . I am 18yrs old my last menstrual period was nov 25. I had unprotected sex from nov 29- dec23 every other day or every two days I started prenatal vitamins dec 1st .. I am really looking forward to having a baby me and my boyfriend really want to start our own little family.. I took a pregnancy test dec 23 but it was negative, could I be pregnant I had cramps and spotting but it got heavy for two days then it was just spotting, sore breast, nausea .. Any opinions?
