I have totally given up on TTC. the doctors said my tubes were blocked and the dye test to show that, did not unblock them. so every time I'm even a week late, I don't even think I'm pregnant. I try not to get excited anymore. (I was 2 weeks late a few months back and lo and behold after 2 pregnancy tests, I started the very next morning!) I have given it to God and if He decides its tine, then ill be ready. until then, I'm just using this to keep track of my monthly.
