I stopped taking my bc pills last month my last period started the1st and I had unprotected sex on the 17th which is right around my ovulation date within the last couple days my nipples have been really sore which has never happened before and for about the last week I have had headaches cramps in my lower abdominal area and have been very emotional I'm supposed to get my period on Friday which is in 2 days but im so anxious I can hardly stand it I just took a hpt and it was negative do you think I'm just now reacting to the change in hormone levels from stopping the pill or do you think I could be pregnant please help!!
