My period started Dec 30-Jan 2 (i have a Cycle of about 25-30days its never been longer than that nor shorter its always in between )We had unprotected sex Jan 6 and I was fertile Jan 7 , Ovulated Jan 11 and Im Late .. it was supposed to come a week ago But its the 30th day in my cycle and i still havent gotten it , i havent felt any cramps ,nor breast pain i took a pregnancy testa week ago when it was first late and it was negative then i took one yesterday and it was negative ...i have not noticed any bleeding whatsover (not implantation nor period) so im wondering if I might be pregnant ?or just late
