Military wife

My fiancé wants a baby so bad. He is currently stationed in Seattle and I live in Georgia. He comes home about every 6 months and for a month at a time. But we both will be moving to Germany next year. Before this month we never knew all the science that went into getting pregnant. Lol. But this time I’m trying something different which is tracking my ovulation. We tried on the 8th day,10th, and we are going to try the 14th and 15th CD. I’m still trying to understand the day the egg actually drops during ovulation. I’m trying to take the pressure out of the process and treat it more like a project because the last time I was soooo stressed out and started to question if something was wrong with us. I also started taking prenatal a few months back just to see if it’ll help the environment for a baby. Iv been experiencing some cramps which I never experience during ovulation could this be the egg implanting to the uterus or am I over thinking it?
