We may have another miracle!!!!!!

I can hardly think straight....but I have to keep my wits about me until we know for sure. Yesterday (at 8 DPO) I tested with Confirm (I have been testing since 7 DPO....as usual...I am addicted to those things). Well it was negative. I even called Paul at lunchtime to have him check it to see if a line showed up (it took several hours to show up last time I was pregnant) and he said "no, there is no line....wait a minute......*pause*....no, there is no line." Bummer. But when I got home last night and looked at it....there was a line....very very faint, but there was a line! So, I immediately took another test and within an hour, I could see what I thought was the start of a very faint line and within 2 hours, there was definitely a line there. I called my RE and left a message asking to come in for a blood test. Then I couldn't sleep the rest of the night. I took a Clear Blue Easy test a couple of hours later and it was negative. Then this morning, I took another Confirm and it was negative too. So now I am a little nervous. I know what a negative test looks like, and I know what a positive looks like. I am just afraid that there was something wrong...why would I get a negative this morning? (Although I had very little urine...I think I used it all up last night. ) My breasts have been sore since 5 DPO, I have been having mild cramping for 2 days, and have felt slightly ill at times...all of which could be explained by other things. So, I went in for a blood test this morning and by 4:00 pm today (when the beta and progesterone tests come back) I will know for sure. I am so anxious and happy, excited and scared. I am just so afraid to believe that with my age (36) and DH's sperm count (5 million/ml with 32% motility and sperm antibodies) that we may really be pregnant again. Oh please, Oh please let it be true.
