we have been trying for almost a year. After not getting pregnant for 10 months I visited my dr and he told me which days to have intercourse which was slightly different than Glow. My next period was spotty and just for assurance I took a test which I assumed would be negative and it wasn't! A little faint line appeared I was escatic! I yelled for my husband and he didn't believe this super faint little line. I took another the next day and a much darker line appeared, this time I kept quite and the next day was my husband's birthday. let's just say he had "the best birthday ever" as he stated :)
