Feeling really uneasy

I am being crazy and have been taking an hpt almost every day since our BFP (I got a bunch cheap off the internet)well yest. the test line was so faint, I figured it must be because I peed like 6 x in 1 hr. Did another and that one was a little darker. Figured the one I will do this am will be nice and dark. Well it is soo faint...like they are getting fainter. This freaks me out (I shouldn't have done this to myself). I am 22 dpo today so the HCG should be nice and built up, I keep waiting for the strong test line. I am so afraid that this means my hcg is decreasing or has decreased.
My cramping went away about 5 days ago, I still get occ. twinges here and there (just had a few a few minutes ago), I am tired, but also have a yucky cold, I was bloated in the beg. now feel better, I might have had a moment or two of nausea, my boobs are sore (I was putting on prog. cream for a week or so and in the past that had made them sore),peeing more, but for the most part...nothing. I almost wish I had m/s so I could feel pregnant. I am so worried. I have to keep reminding myself that I'm pregnant, yet I just don't feel like I am, physically or mentally. This scares me. I belong to lots of message boards for women due in Sept. and it seems lots of them don't have any sx yet. I am 5 weeks now(FF= 5 wks/ 4 days, expecing brd = 5wks/ 1 day)so it is still really early. I just pray so hard with all my might that our little one is in there, he/she hangs on tight and is well. I want nothing more then to see our little on on u/s on the 30th and then I will believe it is true. GOD please watch over us and our little one.
