On CD 16 and 17 I started spotting pink when wiping and brown when checking my cm lasted a couple hours then stopped. Then today CD 17 started back spotting but a little redder lasted about 30 minutes then stopped. I have a 24 day cycle usually ovulate on CD 10 or 11 but never got a positive opk this cycle unless I missed my surge what could be going on I'm nervous since having an ectopic 3 years ago. The pics is from today CD 17 yesterday was more pink and brown. Top pic was wiping bottom pic was checking my cm. Ovulation bleeding? Implementation bleeding? Something else?
