So we have been trying to conceive for three years, I have really irregular cycles and because I'm overweight I don't get any help (my own fault I know) I have worked really hard to loose 4 stone and we tested positive for ovulation yesterday  I was starting to get so worried I was broken, any way - I think I'm slowly loosing it because today I have been really tired nauseous and dizzy it can't be anything serious right? Is it time to accept its not going to happen for me and give up? Not sure I can take another let down
