My period isn't normal..

Cierra
I took my nuvaring out Friday the 29th of July. I started bleeding very lightly Monday evening after taking it out. I thought my period would get more normal throughout the week but it's been very light and I haven't had any other symptoms besides very slight cramps. I had my wisdom teeth out Monday but I haven't been on any narcotics so I didn't think my period would be affected. I don't know if I should take a pregnancy test or if my period is just being abnormal for no reason. Help! 🙏🏼😁
