Confused. Help! Positive or not?

AF

This morning at 5:30am I took two pregnancy tests-both first response. One shows a veeeeeeery faint line (#1), but the other one was negative (#2). They were taken at the same exact time so I’m not sure how this could be. If I didn’t take two, I’d be ecstatic right now.

Fast forward to now at 4pm, I just took two more, but both negative. I was able to hold my pee for 4 hours. Could it be that enough hcg wasn’t able to build up in that time? I swear I’m pregnant. Period is supposed to be here tomorrow but I strongly doubt it will come. I’ve got all the signs. Will take another tomorrow morning but I wanted to see your thoughts. Thanks for your help!!
