Assalamu alaikum,

Your fast is valid as the intention was made correctly before athan and y didn’t nullify it.

This morning I got up for suhoor,I was in the bathroom before fajr time when I was rinsing my mouth,I was trying to swallow something left over as I wasn’t clear if it was possible to take out.so I thought that action ruined my intention and I said whatever I’ll just renew my intention when I got out fajr had entered so for sure all this happened after athan by couple minutes. Is fast valid
