Help!!!

So on Saturday april 22nd, I started spotting and that lasted for about 2 days. And on April 25th was a little bit heavier ( a little bit more reddish but not my normal bright red) and that stopped and the 26th it completely to completely nothing. I was supposed to get my period between the 16th and 18th of April and me and my husband did something on the 15th. I normally have very heavy regular periods but this was totally different. I was thinking maybe we interrupted my period or something but I’m not sure. Anyone have any advice???
