Help guys! What does this mean??!

Hello everyone!

I have been on clomid 50 for 7 days and 3 fsh injections and had only follicle. I got the trigger shot on cd15. Had all the symptoms of backache and chest pain and feeling gassy and so on. On day 30 I started spotting and today I have a light flow with no clots or cramps. Could this be implantation ? I'm tired of these injections and was hoping this would be our month. Any input is appreciated!
