Trigger Shot

I received my first trigger shot Jan 23. Along with this I was on clomid beforehand. They started me on progesterone suppositories too. I had faint lines on home pregnancy tests up until say 7. Today im five days before my period and im experiencing slight cramps and feeling like AF is coming. I have very little spotting. I am 8dpo is there a chance I can get a bfp after getting a negative today?
