early signs of pregnancy?

I think I have a great chance of being pregnant. Im not late yet for my period, It would suppose to come in 2 days. For the past week and a half, I have felt like Im getting the flu.. body aches, sore breasts, a light crampy feeling and a swollen abdomen. I feel really werid and definitly not myself. I have not been pregnant before, although I believe once I had a chemical Miscarriage, I got my period really early and it was so bad, the pain was the most i have ever felt, and there was so much blood. I didnt feel like this at that time. I just hope its not me trying to think pregnant to feel these symptoms! is that possible, or am I experiencing too many symptoms before.?
thanks!

You can take a pregnancy test 5 days BEFORE A missed period. You need to get a 'first response early detedction", or another early pregnancy test that tests before a missed period.
