Implantation, Letrozole, Ovidrel

Elizabeth

I’m 7 dpt and 6 dpo and I had some spotting earlier today. This cycle I took 250 mg letrozole cycle day 3-7 and I did my ovidrel trigger last Friday. I had one follicle at 20mm. Has this spotting happened to anyone else on these medications around this time frame? Of course hoping it’s implantation but is it too soon? Is this af? Is it just the meds? My neerrvvesss are a wreckkkk. 😫
