Excited but scared! We are pregnant with our second child. We have been trying for more than a year. Last August we had a miscarriage at around 6 weeks. It destroyed me emotionally. Everyone around us kept getting pregnant even right after miscarriages and I was so afraid we'd never conceive again. Our son is almost 5 and we conceived him so easily. Anyway we are here and I'm almost 6 weeks and still can't shake the anxiety that I'm going to miscarry again. Last time, the miscarriage started with blood when I went to the bathroom one morning. Now I literally shake and get  nervous every time I have to pee. Anyone deal with anything similar? Tips on how to chill out?
