Confused.?.

💙Shadoe✨ • Just conceived our rainbow baby:) M/C in March 14 & chemical November 14... Going to marry the man of my dreams<3 After 14 months of trying finally got our BFP 8/7/15! Praying for a sticky baby🚼
I got off depo in June. It only took until August to have regular cycles again. I never spot in between periods. This month has been different tho... I started spotting on the 10th, then had my regular period. I was finished with my period on the 16th, but have continued to spot ever since (today is the 23rd). The spotting varies daily. Some days its just traces, and others its a little more, but never like period flow. I have been having some symptoms, like sore breasts, and nausea, cramps, and emotions... But none of these symptoms are severe. Anyone know what's going on? I have attached a pic for reference...
