Could this be my positive or still my trigger shot? 13 days post trigger

I did my trigger shot 23rd I tested Friday at 10 days post trigger got nothing tested Sunday 12 days post trigger got a very faint can barley see in picture tested today Monday 13 post trigger and I have a very faint positive. Could it be the trigger shot or is this finally my BFP. I’m not scheduled until next Monday for my beta. Since yesterday I’ve been feeling really moody and today I’ve been really nauseous and I threw up. I don’t wanna get my hopes up in case my beta comes back negative. Any advice?
