Am I pregnant?

can any one tell me what are some signs that you can not get pregnant because the last 5 to 6 months me and my boyfriend have been trying to have a baby and I am not sure why I have not got pregnant yet but something weird things have been going on because my lat period was on April 18th and my next one was due on may 16th but on may 1st about 2 weeks after my period went off I had some mild cramping and then on the second notice I was bleeding similar to my period that lasted for 2 days and I know it was not my period because it was to soon at first I thought it could be signs of a miscarriage but I knew it was not that then I was supposed to receive my period on the 16th of may but it did not come on and a week later on the 23rd I was cramping and bleeding like I would if I got my period but the bleeding only lasted for 3 days when my normal period last for 5 days so can some one please help me could I be pregnant

If you chart your cycle you'll have a higher chance of conceiving.
You COULD be pregnant, go to your doctor and get a blood test done.

ok no laughing when I say this. I always thought that the once your hymen is stretched that means your period can come out like more than before. I mean like normally I have my period for a week but now I only get it for 4 or 5 days.

maybe you are =] take a test
let me know
