TMI - Chemical pregnancy??

Good morning! So today I’m 19 DPO and don’t have my first ultrasound for another couple weeks so I’ve been taking HPT every couple days for my own sanity. Well I took one on Monday evening which was 17DPO (top test) and another this morning with FMU (bottom test) and I feel like this mornings lighter? Also I had some weird discharge this morning too, TMI sorry (picture attached). What do y’all think?
