Good thoughts and prayers for you and your precious baby. Keep your feet up.
I went through the same thing with both my kids. My first one was very light spotting, but with my second one, I thought I had already lost her. I had heavy bleeding for almost a week. It turned out that I had a blood clog. Doctor just had to keep an eye on it as it could cause to go into early labor, and even that didn't happen. What I am trying to tell you is, don't think the worse. These little boogers tend to make us worry even before they are born. He/She is just trying to give you a taste of what is yet to come ;-). Stay positive!
