First time embryo transfer questions

This TWW has been horrible! I am just so anxious about it not working all the time. I’ve had some mild cramping, on and off sore boobs, and fatigue which I know could be the medicine or early pregnancy symptoms. I go in for my beta test on Monday and I should have waited but I was feeling really positive since I have a cramping/pulling sensation pretty consistent all day. I woke up from a nap and decided to take a FRER test because I was pretty sure I would at least see a faint line but it was starkly negative. I’m trying to remind myself it’s early (9dp5dt) and I didn’t use first urine of the day. Trying to stay positive. Would love to hear any success stories about negative home tests and positive betas. Thanks!
