We have been trying to get pregnant for about 4 months and I got my bfp on Wednesday night. My periods have never been consistent and the first 3 months of trying we would "try" the week that it said I was fertile then the following week lay low. After it didn't work I decided to continue to "try" every other day the week it said I was fertile and the week after. And that's what seemed to work. Due 8/8/15
