Continuous diarrhea for 2 weeks after AF-BFP?

M

Diarrhea Started with AF and is still ongoing! I’m miserable and don’t know what to do. Even drinking water is causing me to run to the bathroom. Is it possible the AF was actually implantation and this is 2 weeks of diarrhea afterwards? I’m too defeated to test for pregnancy to see a negative every single time.

Advice?
