had my quad(?) levels checked. need advice!

Al
I went in to the hospital last night because my cramps were becoming slightly more severe and at times actually hurt! I have history of my progesterone levels not rising and they think that is what resulted in me not being able to get pregnant for so long. The checked my quad(?) and my number was 404. He said that is a pretty in the middle number and that either means I have been pregnant and lost the baby so my numbers are starting to decline or I'm very early on in my pregnancy. My last period was November 10th but I have super irregular periods and I could be anywhere from a couple weeks to 8 weeks pregnant. I have to go in tomorrow and have my quad drawn again to see if the levels go up or down and I will find out at my dr appointment on Monday. 
Has anyone had this happen and they ended up having a full term pregnancy and everything was ok?
