Doctor, I am on progesterone tablets frm cd 19 10 mg twice a day. I ovulated between cd 20 amd 23 did a scan and there was POD fluid present. I was due on march 2nd but on 1st I was spotting brownish red few drops just once in a day if I run around too much or press on my abdomen. I have PCOS. Also I have watery cm today. Could this be implantation bleeding or impending periods? Could still be pregnant? Should I continue the duphaston tablets? And wait til 14-16 dpo.
