PMS-like symptoms, but most likely not pregnant?

Am I most likely pregnant? (repost-more symptoms)?

• I think I may be pregnant but it could also be my period. I had unprotected sex, he didn't pull out, on the 6th of this month. I had two periods last month, one the 8-12 and then 26-31. This month I have not had a period yet. It's been a month since my second period, and nothing. For the past few days I've had really bad cramps on my sides and where my uterus is. My lower back is KILLING ME. And I have massive headaches, and I feel different. Also I've been having hot flashes, I'll be sitting in a room and be sweating. So I took my temperature it was 98.5, usually my normal temp is in the 97 range. It hasn't gone down, I'm gonna continue to check it every morning. I was planning on waiting a couple more weeks to see if it comes but idk. Does it sound like I'm most likely pregnant?

• Answer:

  You won't have symptoms this early if you are. If your period is late, then take a test. If it comes back negative, then you're not pregnant because they can detect them after you miss your period. Your back won't start killing you until a little later in pregnancy.
