I am on CD 19 and I think I have had fertile CM since CD 16. Hubby and I have made sure to take care of business during this time, but now I am doubting whether I am seeing fertile CM or semen. Any tips on distinguishing the difference between the two? How long after sex can semen still be seen after wiping when using the bathroom? If I am still seeing fluid that may be either type of fluid (semen or CM) 30 hours and even longer after sex, could it still be semen? Sorry, kind of graphic questions but it's really hard to know the difference! Thanks for the help! Also, is it possible to "feel" ovulation? I have felt a sharp pain below and to the left of my belly button for the past couple of days...Thanks!!!
