Hi lyn,
if you feel so stress abt TTC, why don't u stop doing everything, don't care about when u ovulate, just enjoy the married life with your hubby and make love as and when the passion arises. In the end, if you have bb, then it will be a blessing, if not, don't be too affected and disappointed by it. I know it's easier said than done, me too has been trying to be like that, but sometimes will be too overwhelm by the TTC thing.
