Need opinions!

Ok so on October 30 I got my period and it ended November 3. We had sex twice once on the 9th and once on the 11th of November. Then November 17-21 I got what I thought was a period was lighter then normal and didn't have clots like normal. Now I'm three days late no sex since those days (I know very sad lol). Should I test or is my body just being dumb. We have been trying for five years with three miscarriages so I don't want t get any hope what's so ever
