Firstly, try to relax like trynig43 said unless you are bleeeding or severly cramping.. you are fine.. Secondly, STOP READING THESE FORUMS!!! hehehe enjoy your pregnancy hun.. filling your mind with the stories in the miscarriage forum is not going to help you.. unless you have reason to believe something is wrong, i honestly would stop reading the miscarriage forum.. i can certainly understand your fears I have the horrible habit when something is good always drawing myself to the possible negative outcomes and it never does me any good... Congrats and I wish you a happy and healthy 9 months :)
As long as u r not spotting or having severe pain things are fine. Its hard not to worry with it being ur first. Try and relax and enjoy ur pregnancy because when baby gets here the work begins. Lol congrats and good luck.
