Trigger shot questions

Lauren

I’m 10dpt and probably 7/8 dpo from the ovidrel 250 trigger shot. I took 150 mg of clomid and 7.5 mg of letrozole together. I had a 17.5 mm follicle and triggered that night. I’ve been trying to test out the shot and today I got this on the Walmart cheapie but then what looks like a negative on a FRER. I’m all confused 🤷🏼‍♀️
