Should I test??!!!

Today is 7 days past my frozen embryo transfer and I’ve been soooo good not testing yet. But I don’t know I can handle it anymore, especially since I feel my period coming. I was going to test tomorrow morning with my first morning urine but I honestly don’t even know I can wait until then. I also don’t want to test right before work tomorrow, get a negative, and be so upset moments before I have to go into the classroom and be a teacher. So that’s also why I’m thinking of testing tonight. If it’s negative I can at least have an evening to wrap my head around it. I bought the expensive tests where you can test well before your period comes lol. BUT Will my Urine be too diluted to pick up any HCG if I test tonight or am I far enough along since I’m 7dpt today… and if this matters, my trigger shot was 10/9 (so 14 days ago).
