My ovulation date was February 5th, but I’m not sure why I haven’t seen enough discharge on ovulation day, I have been feeling more tired and different feelings of cramps for several days , no spotting yet just normal discharge you can bearly tell I have discharge , I’ve been off of birth control for a year now , I just got a regular period after so many months Jan 20th .. I’m trying to get pregnant, I have a 4 year old why is it so hard now to get pregnant? Help!
