In Australia, More + HPTs But Scared...

I have taken several more CBE and one EFR HPTs since yesterday morning....and all showed very light positives (even the EFR which had been negative yesterday morning). However, it just seems that they should be darker by now (10dp3dt) if this were a viable pregnancy. I am almost thinking it could be the HCG from my trigger shot (15 days ago?) I am just so afraid to allow myself to be happy. I am so afraid....but I so want to be happy. Please keep us in your thoughts and prayers.
