Implantation bleeding? 🤞

Tori

I’m 7 DPO and 8 DPT (Pregnyl) and had some cramping and a couple of shooting pains (very brief) last night in my lower stomach. Have felt kinda nauseous (but I can get nauseous with my cycle and stuff so it could be nothing, and Pregnyl makes me nauseous). Could this be implantation bleeding?
