Unsure 😕

Hi ladies, so I’m normally never late (the last time I was late was my first cycle off of BC), and I’ve been having unusual symptoms (nausea, increased appetite, etc ) but I’ve taken 9 (yes 9) tests this cycle (two today) and all seemed BFN. They’ve all been the “cheapies” because we have so many here in the house, but i was really hoping to surprise my husband today (it’s our anniversary ) , is it worth it for me to buy a FRER test? Or should I just wait it out and see if af appears?
