Okay well, I am really confused. My actual first period was January 3rd, 2015. It lasted about 5-6 days. January 18th and 21st I had unprotected sex. He claimed he came but I do not know for sure. On January 26th I started bleeding. Usually it takes 30/31 days for my period to come on. For 2 days. After that, it was mainly spotting. I woke up, and I was not bleeding for 12 hours. Then I bled again. It was a on and off situation and lasted for 3/4 days. I am now starting to feel nauseous at times, weird cravings, urinating a lot, lower back pain if I stand too much, headaches, really sore breast, very emotional, dizziness, and constipation. Am I pregnant? I really have been trying...
