finding a Cycle Buddy-LMP 8/14

hey!!!! so the first day of my last period was August 14th. my husband and I BE everyday during my fertile window. I dont have many symptoms and I'm starting to be pretty certain I'm not pregnant this month.. i have sore, and HUGE boobs!! I did have some cramps like 2dpo or so but nothing like really noticeable more like me picking out symptoms. I would love to find a Cycle buddie. I haven't tested yet and would love to know when a good time to start testing is.
