Cramping and spotting

Hello ladies it’s been awhile since I’ve posted. For the past couple of weeks I have been focusing on losing weight, cervical health and my fiancé speed health before we start trying again.

My period ended on the 3rd of this month, I am currently on CD 15/16. Today I started having dull backache, a sharp pain in my right pelvis and followed by some bleeding/spotting (reddish/brown). Right now I feel like I’m on my period.

According to glow I’m due for ovulation in November 16th. What’s going on? Should I see a doctor?
