Spotting

I just need to get it out and tell someone because i feel like I’m going crazy sitting here just thinking about it and I could use some good stories. I found out yesterday I was pregnant with baby #2. Very excited and happy, told hubby and my parents (we live with them so they’d know very fast). I’m started spotting light pink a few hours ago... no cramping but I’m so scared. I had a miscarriage a few years ago and all I can think about it losing this baby. It’s super light but being only 4 weeks I know the chance of MC is so high. Any words for me?! 😕
