Hello. I have irregular periods, but just had one end just about 1.5 weeks ago. I'm not on birth control, regularly have unprotected sex but he pulls out. Yesterday, I have pink sticky CM, and light cramping. I still have some sticky cm today, but it's clear and it's much less. Still had very light cramps this morning, not one sided. My first thought was I'm approaching ovulation, but then I read that it shouldn't be pink. Also, my cramps and very dull and are not just on one side. Could this be implantation bleeding? Ovulation
