Hpt after hcg trigger shot *pics included*


I got a hcg trigger shot on 11/28. I tested that day when I got home. Then again on 12/5 and this morning. The plan was to test out the trigger but my lines seem to be getting darker. It seems to early for my bfp but I am perplexed as to why they are not getting lighter. Im afraid to get my hopes up. They are the same brand of hpts too. (from left to right: 11/28, 12/5, 12/6) I will test again in the morning . Could this be the start of my bfp…?
