Okay so sometimes I get myself in the "mood" before I bd with my so. I have a toy and when I looked at it I had clear stretchy cm on it. I don't have a lot of cm cus that's just how I am. Is this true cm or was it cum from ya know.... Especially since I just got of my period like 2 days ago. Could I ovulate and have fertile cm that fast after my period?
