Im so interested in this that I need to try it out. I have been pregnant five times and im 90% sure I've caught this month. My body is telling me I am but of course I may be wrong. I always get sore boobs like a few days before af but I've had them since 1dpo along with extreme tiredness. Like crazy fatigue and nausea. So im 6dpo today and just done an opk and hpt of course hpt was negative but had a line on OPK but not strong yet but will be testing everyday to see if they darken.
