Please some advice

I'm on cycle day 48 my last period ended on dec 13. I usually get sore breasts before my period and bloating but that hasn't happened at all ! I spotted last Sunday, Monday, dry for the rest of the week. Then this past Thursday it seriously felt like I started my period but I only heavily spotted for 4 hours and have been dry since. Should I take a test? Me and my Bfriend never wear a condom we use pull out method and I'm not on BC ? Please someone give me advice !!!!!
