Hey, I've just found out on Saturday I'm pregnant with Baby no 2. I'm so excited and I new straight away because I had instant symptoms that I'd experienced the first time. So I did an early clear blue test and I was right, it's positive. I'm just about 4 weeks, so really early yet. But I've just had a little light spotting, I never had this this with DD. How do I know the difference between early pregnancy light spotting and if I'm miscarrying?
