Anyone have some suggestions?

Kr

I am 10DPO had some cramping, nausea the last few days. I took a test this morning BFN. However, my dog stepped on my lower stomach this afternoon, and I have had crazy cramps since. No idea what this could be. Anyone have any suggestions, or what I can get them to do to subside? I don’t want to take anything, or use heat in the off chance that I am pregnant and haven’t received any confirmation yet. I’m completely lost.
