Going to get my HCG levels tested

So around 3:55AM this morning I was thinking of my dogs Princess , prince, and Princeton my three peas in a pod I call them I guess I was trying to take my mind off of my HCG levels. I was my nervous today than yesterday I didn't tell my husband because i know he's nervous too. We tried to talk about but we just got sad about it because we know in the past it wasn't easy getting no your not pregnant or seeing a negative pregnancy test. I couldn't understand why the regular pregnancy test couldn't pick up a pregnancy but the 5 day sooner test did but the lines was faint. It scares me because I know last time it was faint but not like this I'm scared that my levels will say to low or not pregnant. My doctor will call me later today to tell me about my results I hope it all goes well
