The start of my last period was July 1 and was regular today is august 7 and still no period. I was on birth control I went off the pill usually my period starts with in 3 days of stopping the pill got nothing 6-7 days later I had brown spotting more Mucus then spotting that lasted two to three days. That was about the first or second of august. To this day I don't have any more spotting and still no period. And yes I had unprotected sexual intercourse about a week before my period. I've had swollen boobs, heightened sense of smell, cravings, bloating really bad mood swinging, very emotional and headaches. Any clue what could be going on? I've had two negative tests............... what should I do? I'd appreciate any advice and thoughts!!

Thank you!
