Faint positive Clear Blue Easy +/- followed by negative

So, my husband and I have been ttc for 6 years now and I am a HPT freak and would love to be pregnant more than anything in the world!!  I have had a few miscarriages in the past and sometimes think I have signs when I don't.  I have taken every test there is in the past and Clear Blue Easy has been the most accurate.  I have a very irregular periods and not sure when I ovulate.  I always think I am pregnant just to be disappointed a few days later with negative hpt's.  Recently, I took a hpt on 5.18.11 in the afternoon and I could see a faint positive 20 min later.  On 5.19.11 I took another one in the morning and thought I could see a faint positive within the specified time frame (see above freak to get pregnant comment) and just went to work.  When I came home about 10 hours later (I already know you're not supposed to look at the test after 10 min, but I am a freak) there was a very bright blue solid like where the positive sign is but it was only half the normal size.  Then I took another test 5.23.11 am and it was negative but I still have the same signs and no period.  I have SO many symptoms you would think I would just know, but as I said, I want this so bad that I do not put it past myself to think too much into it.  Here are the tell tell signs (TMI warning)...
- Bloated all day
- Noxious on and off all day
- Food does not sound appealing at all
- Bad gas
- Clear mucusy discharge on and off
- Mild headaches
- Tired most of the day
- Cry at everything
- 1st day of last period was 4.15.11
I need any kind of help I can get at this point.  I am stressing myself out over this and, with my pregnancy history, this is not a good thing.  I am so scared that I read the test wrong and I really need any kind of advice anyone is willing to give.  Thank you so much to all in advance!!!  :o)
