Anxious during pregnancy

Al

Does anyone else feel anxious about there pregnancy? Everytime I feel a cramp or twinge I start feeling so anxious like something is going to go wrong. I'm 22 weeks and have just had my 20 week scan so I no my little girl is growing perfectly healthy. My mother had a lot of complications with Her pregnancy's and I think thats just always at the back of my mind. Does anyone have any tips on how I can relax and enjoy every moment and stop worrying.
