Advice please

I'm currently 6 weeks and 3 days due around 30th March 2017 Iv had no cramping all weekend and then today it's started up again is this normal? Everytime I feel something down there I rush to the toilet to make sure I'm not bleeding as I have had 2 previous miscarriages! Someone tell me I'm going mad! I really want to enjoy this pregnancy but I can't so far 😭😭😭
