Should I test or not ?

I 22F diagnosed with pcos 2 yrs ago recently had a miscarriage on july 17th , my cycle came back at the end of August on the 28th. I ovulated a week after my period, and my husband 23M was home during ovulation.(* for context I’m a heavy bleeder meaning I usually have to wear a depend til the last day of my period as well as bad cramps *). So here comes the question should I test or not? This time my period came 4 days early and was very light and a rusty brown color no cramps and only had to wear a panty liner. As of yesterday I woke up nauseous checked my temp and it was normal so now I’m in a state of confusion like was that my period or something else. **Side note I’ve never had an early period either
