I went off my birth control pill June 23rd started my period the 25th then it ended a few days later. I had another period starting July 3rd for about four days. I had unprotected sex from June 25th - July 13. It is now August 3rd and I have not had a period. I have felt like i am going to start but I havent. I have had cramps for like three weeks on and off. All I have is a discharge that was lotiony but now since iv been late its cloudy and watery. I took a pregnancy test this morning and it is negative. COuld I be pregnant or just messed up from going off of the pill?
