Ok, this is going to sound really stupid but here it goes.. I've had three kids already, and had a miscarriage before actually 2 before. I am about 5 weeks I think(I got the baby bump going ) and I'm scared that something will happen again,especially since the line of work I do... I've had all the symptoms, the extreme tiredness, backache, cramps, which I get time to time when I'm at work, boobs seem fuller and tender. Any advice to try to think really positive??
