Could this mean I'm pregnant?

Ok, so I just found out (thanks to YA) that I am 9 dpo. I took an early morning HPT test and there is a very very very slight line, I really would need to use a magnifying gl (which I don't have) to be sure, but if I hold it to the sun I think I can see something extremely faint on it. BUT I had taken a trigger shot which was giving me positive tests up until yesterday (faint but definitely a line there). I also took an opk test today and on that one there is no doubt it is a BFP. So, does the opk carry much weight? I can't wait to test again tomorrow. I was heartbroken after the HPT but now have some hope after the OPK. Does anyone have experience testing both types of tests for pg detection? I know the OPK only detect LH but still...
