So I found out this past Wednesday that I'm pregnant. AF was 2-3 days late. So I'm estimating that I'm only around 4 weeks or so. I noticed that I was spitting a couple days before my missed period, which I'm assuming was implantation bleeding. But I'm still spotting now. It's like a brownish color. Some days I only notice once while wiping, and others I notice it a few more times throughout the day. Is it normal to spot this much or is it bad? I'm kind of freaking out!
