22w3d--Still spotting

Today was my last day at work. Tomorrow I am planning on doing nothing but resting to see if this spotting goes away. I can't believe it's been going on for over 1 week already. The strange thing is that they can not find the source. I don't know if that worries me more because the dr's say everything is perfect, but I just think it's strange. I know that there are some women that spot and/or bleed during their pregnancies, but it is still something to worry about. I guess I just don't want anything to go wrong, especially at this point. I love Natalia so much already that I honestly don't know what I would do if things were to go wrong; I would probably go crazy! I pray that everything is well. St. Gerard, please protect Natalia and that she may brought to this world healthy.
