Pregnancy Info HOME

My boyfriend and I don't really use protection. We had unprotected s_x 1 or 2 times around August 20. My br___t began to hurt me not too long after. On Sept 4th, my period came which i found perfectly normal. It left on Sept 10th but my br___ts never stopped hurting which was a little unusual. Some time later I experienced mild cramps specially where my right ovary is and then just mild cramping. Then, I had two days of brown spotting. I also noticed that I'm peeing a lot more often than usual, one day by 12 pm i had already gone 4 times. My period was due to come oct 2, and still hasn't arrived and today is the 10th. Every day for the past two weeks, I've been waking up with mild headaches and having dizzy spells throughout the day. sometimes i also feel a bit nauseous. All HPTs have come back negative though. Could pregnancy even be possible with my situation? please help me someone anyone!
