Bad feelings

Katrina

So, I had a miscarriage 6 months ago, and the entire duration of that pregnancy I felt like something was wrong, and we lost that baby. Fast forward 6 months, and we are pregnant again. Up until the last few days, I felt like everything was okay. Now, I have that horrible, nagging feeling again that something is wrong, and will end in another miscarriage. Has anyone else ever had/experienced these feelings?
