hello i had unprotected sex on 8/5/10 and my period was due on 9/5/10 and i came on it as usual. however it was a bit lighter than usual and i was worried if i had become pregnant, although many say that if your period came as normal you are not pregnant, and it wasnt within the few days which im fertile. i am still at this stage really worried and stressed about it, my next period after that which began 10/6/10 and finished on 15/6/10 was to a bit light, but i wondered if that was because i have been stressing my self about it. i went to the clinic on 27/5/10 and my test came back negative, and the doctor said there was very little chance that i was pregnant and to wait to see if my next period came in which it did (luckily). i have been getting a few symptoms of pregnancy e.g. tiredness, stomach pain, constipation! although these symptoms can relate to stress and anxiety symptoms also! please please please help me, i'm worrying myself all too much till i know for certain :(
