5 weeks today and since yesterday I've had a little bit of light brown spotting and occasional sharp twinges in my uterus area. Worried sick and trying to understand what this could be if not the start of a miscarriage. Lost my first pregnancy at 10 weeks just a few months ago. It was a so called missed abortion which meant my body just pretended like nothing had happened and I only found out by chance because I was granted an early ultrasound. Needless to say extremely worried it is all happening again. Any experiences or advice greatly appreciated!
