My period came on the 5th March 2015. It finished on the 12th. On the 22nd I saw a light pink discharge that slowly turned to brown but stopped in the night. On the 23rd it started again but light. Additionally, I am feeling the need to climax frequently. I don t know what wrong. Could it be I am pregnant? Or just ovulated? Ps I had unprotected sex last month around the time I was ovulating and the sperm went in me.
