I'm pretty early in my pregnancy Iv already had bloods done and confirmed by doctor I'm pregnant I'm only about 4.4. My problem is I fear of miscarriage ! I'm a first time mum. Iv taken parental vitamins and follic acid for 3 months before we tried I'm continually taking it everyday. I'm getting enough nutrient I take multi vitamins aswell. I take really hot showers which I read can raise your temp which isn't good. Just any ideas to calm me or anything please !!! I'm leaving country to go on my honey moon for a month aswell
