7dp FET BFN - should I test again?

RAS • Mommy to Mila Rose 9-2-18 & Isla Lily 03-21-20 🎀💗🙏🏻

I did my first <a href="https://glowing.com/glow-fertility-program">IVF</a> and did a FET transfer exactly 1 week ago today 10/30 7 days post transfer. A lot of woman tested between 5-7 days and got BFP, I used a cheap dollar store one apparently the girl at the store used it and said they were accurate for her. I thought whatever I’ll give it a shot. Obviously I’m sad and was crying but not sure if I should test again? My official test date at the clinic is next Monday. I do have a clear blue pregnancy test that detects weeks but I wanted to save it when I actually got a BFP. Feeing like shit now 😕 this is why I didn’t want to test and I barely do HPT just always waited for my period to just come
