Looking for a cycle buddy...

My husband and I both turn 21 in December this is first month of actually trying. Right now i stay at home but I'm going to school for my vet assistant. I'm not sure if I'm going to be always a sahm but I might be. My husband is active army and we are about to go through our first PCs. I just had AF on 9/19, and my fertile window is coming up (I think I ovulate sooner though.) I'm a 28 day cycle but can range up to 31 days.
